We are moving our processing from an older super computer to a new one here at Indiana University. Preliminary testing is showing a significant difference between final summary stats results between subjects processed on the old system versus the new. The version of freesurfer on both systems is identical. Comparing the logs of the same subject run on both systems, I've found that the differences seem to start with the mri_watershed function specifically the main basin size. For the same subject we find: Old computer: main basin size=22667431830 voxels, voxel volume =1.000 = 22667431830 mmm3 = 22667431.936 cm3 New computer: main basin size=22208239350 voxels, voxel volume =1.000 = 22208239350 mmm3 = 22208239.616 cm3 As you can see they are very different. My theory is this is propagating through the rest of the process and giving us different summary stats at the end. I should note that both aseg and aparc stats are affected. I am also enclosing the logs for both runs as well as the differences found through the diff command (this is a lot parse through as even time stamp differences are picked up). Essentially what I am trying to find out is if these differences we are noticing are typical when changing computers and if not what could be causing these differences that I may not be picking up on.

[Freesurfer] WM editing and longitudinal processing v5.3.0
Hi, From what I can read in the wiki about wm editing, I understand that edited wm voxels have values of either 255 (added) or 1 (removed) and no other values. These are stored in the file wm.mgz. Is that correct? Before processing a lot of data I want to be sure that running recon-all with the option autorecon2-wm will recognize these voxels, also during longitudinal processing. Can you confirm this.

Re: [Freesurfer] WM editing and longitudinal processing v5.3.0
Hi Bruce, When I have a look in the recon-all script I see that it is tested if there are voxels present in wm.mgz with value 1 or 255. Both indicate wm editing. The comment in recon-all says that 1 means remove and 255 means add. And concerning my second question: are these edited voxels correcly processed with the option autorecon2-wm and subsequently with longitudinal processing?

Re: [Freesurfer] WM editing and longitudinal processing v5.3.0
Hi Martin, One thing I want to be sure of: should the edited wm voxels really have a value of either 1 or 255. In previous versions an added wm voxel had a value of about 110, this is not anymore the case? I'm asking this because I want to edit wm by using results from another application that segments wm, so not by means of manually editing with freeview.

[Freesurfer] Recent paper on FreeSurfer reliability
Dear Bruce, Doug, Nick, and other co-workers, As authors of the recent paper “The effects of FreeSurfer version, workstation type, and Macintosh operating system version on anatomical volume and cortical thickness measurements” we would like to take the opportunity to respond to the numerous e-mails and reactions written on mailings lists and websites. We have never expected that our paper would have such an adverse impact. We have noticed that several so-called “journalists” have misinterpreted and erroneously extrapolated our conclusions. Even though this is not in our hands, we want to express our disappointment of these events and that we feel very uncomfortable with the created harassment. We want to stress that it has never been our intention to put FreeSurfer in a bad light or to blame its developers, rather we wanted to quantify the effects that you frequently warned the users about. The results of our study confirm your recommendations and increase the awareness of such effects to (novice) users. It is of course unavoidable that modifications to algorithms will produce different results; we, nevertheless, must admit that we were surprised that some effects were rather large. We are using FreeSurfer frequently for our MRI data and we definitely intend to do so in the future. We are impressed by the efforts of your team to improve the algorithms and to extend the capabilities of FreeSurfer. We are most grateful to you and the other developers because these continuing efforts enabled and will enable us to perform our research in a valid and proper manner. Unfortunately, the media attention gave the impression that our conclusions would only be directed to FreeSurfer. We have written in our discussion section that some of the conclusions may apply to other packages in the field of neuroimaging as well. We hope that you can acknowledge our sincere intention to examine and increase awareness of uncontrolled variation in MRI data analyses in general and not to pinpoint Freesurfer. Therefore, we have informed also the users and developers of FSL about possible similar effects.

Re: [Freesurfer] different fs versions
Dear Marise and Laura, As Bruce et al frequently warned users about, you should never mix different versions. The effects have been quantified recently by our group, see http://dx.plos.org/10.1371/journal.pone.0038234 I can add to this that the differences between v5.1.0 and v5.0.0 are somewhat smaller than between v5.0.0 and v4.3.1/v4.5.0.

During the course it was mentioned that it is a very bad idea to mix Freesurfer versions during the analysis. However, we did all the preprocessing on an external server, using version 5.0.0 ('freesurfer-Linux-centos4_x86_64- stable-pub-v5.0.0') and we are currently doing all of our group- analysis on a different server, which has version 5.1.0 on it (' freesurfer-Linux-centos4_x86_64-stable-pub-v5.1.0'). Because both servers are used by a lot of people, it will become difficult to do an update on either one of these versions. Will this become a problem, or is there a way to avoid problems while still using these different versions? Thanks in advance for your help! Kind regards, Marise Machielsen, MD. Laura Koenders, MSc.

[Freesurfer] How to register FLAIR to T1?
Hi, I would like to register FLAIR to T1. Specifications FLAIR: axial acquisition, 24 slices, pixel size = 0.45 * 0.45 mm^2 slice thickness = 5.50 mm (no gap). The slices run from the top of the brain to just below the eyes. This is contrary to the T1 scan which covers the full head down to the neck. I have tried bbregiser as follows: bbregister --s 001 --mov 001_FLAIR.mgz \ --reg 001_register.dat --init-fsl --t1 --tol1d 1e-3 and inspected the result with tkregister2 --mov 001_FLAIR.mgz \ --reg 001_register.dat --surf The result looks bad, it is displaced and rotated by about 20 degrees with respect to T1. It makes hardly any difference if instead of --t1 --t2 as contrast setting was used. Is there a better way to do this registration? For instance, should I crop T1 to about the same space as covered by FLAIR?

[Freesurfer] Clusterwise correction for multiple comparisons
Hi, I'm performing a clusterwise correction for multiple comparisons with the command mri_glmfit-sim --glmdir my_glmdir --sim mc-z 5000 1.3 basename \ --sim-sign abs For version v4.5.0 this took about 40 hours to complete. However, for v5.1.0 it is now running for more than 6 days and from the csd file I can read that it still has more than 1000 steps to go. Is it possible that it takes that much time?

Re: [Freesurfer] How to register FLAIR to T1?
Hi Doug, I've found a solution to the problem: I converted T1.mgz and FLAIR.mgz to nii.gz and then applied flirt directly with the same options as in flsregister called by bbregister, so flirt -cost corratio -dof 6 -searchx -90 90 -searchy -90 90 \ -searchz -90 90 -in FLAIR.nii.gz -ref T1.nii.gz \ -out FLAIR_to_T1.nii.gz This perfectly matched the T1.

Hi, I want to apply a cluster correction with mri_glmfit-sim with the --cache option: mri_glmfit-sim --glmdir my_glmdir --cache 1.3 abs It fails with the error message that it can't find the file: FSDir/average/mult-comp-cor/fsaverage/lh/cortex/fwhm34/abs/th1.3/mc- z.csd (FSDir is the directory where FreeSurfer is located, version 5.0.0, Mac OSX10.5) Looking at the content of the fsaverage/lh/cortex directory than indeed, only the directories fwhm01, fwhm02, ..., fwhm30 are present. In the log file from mri_glmfit I can read that the residualFWHM is 34.005014. Since this FWHM is automatically derived by mri_glmfit, does it mean that I can never use the --cache option in this case?

Re: [Freesurfer] Fmri_glmfit-sim with pre-cached fails
Hi Doug, For mri_glmfit I used a cortical thickness smoothed with a FWHM of 20, resulting from using the -qcache option in recon-all.

Re: [Freesurfer] mri_glmfit-sim with pre-cached fails
Doug, For the PCA residuals we found 37% for the first component. The same analysis has been done for FreeSurfer v4.5.0, and we found a residual FWHM of 15.27 and 30% for the first PCA component. The time courses showed some outliers for both versions, very much dependent on the position on the surface, i.e., each time different subjects were outside the confidence limits. Summarizing: v4.5.0: residualFWHM = 15.27; 1st PCA 30% v5.0.0: residualFWHM = 34.00; 1st PCA 37% (number of subjects is 53). So, it is a puzzle why the residual FWHM is that large for v5.0.0.

How many subjects do you have? There might be one that is messed up. You can check this by loading the y.mgh as a "time course" in tksurfer. It will give you a graph with each subject. Finally, you can run mri_glmfit with the --pca option to get a PCA of the residuals. This will create a folder called pca-eres. Look at the stats.dat and see how much variance is explained by the first component (first row, 4th column). doug On 09/28/2012 03:31 AM, Ed Gronenschild wrote: Hi Doug, For mri_glmfit I used a cortical thickness smoothed with a FWHM of 20, resulting from using the -qcache option in recon-all.

Re: [Freesurfer] Problem with glmfit: matrix is ill-conditioned
Hi Doug, It is indeed correct that columns 1 and 17 are highly correlated. However, for another version of the fsgd file, where the corresponding class and covariate values where identical but with other covariates (so leading to the same columns 1 and 17, other columns are different), all went well.

[Freesurfer] Differences in nu.mgz between v5.0.0 and v5.1.0
Hi, I noticed a difference in the file nu.mgz between FreeSurfer version v5.0.0 and v5.1.0 (running on Mac OSX10.6). It looks as if nu.mgz in v5.1.0 is an intensity scaled-down version of nu.mgz in v5.0.0. The release notes tell that a bug is fixed in mri_nu_correct.mni, I don't know if that may cause this difference.

Re: [Freesurfer] ICV differences from version 5.0 to 5.1
Jon, The reason is that already in one step earlier in the pipeline, the nu-correct stage, a difference arises. See thread on "Differences in nu.mgz between v5.0.0 and v5.1.0" Cheers, Ed Hi, We have noticed differences in Talairach registration (and therefore ICV estimates) in some of our subjects from version 5.0 to version 5.1. Please see the attached document. There are 4 subjects, each row represents the same subject, same input images, same recon-all options (-all) between versions. The bottom of the second page has a table with the ICV values for these subjects across versions. Have there been any changes to the Talairach registration step from 5.0 to 5.1 that would account for these differences?

Re: [Freesurfer] coregistration - FA to Freesurfer
Dear Joana, Two things: 1. You should be very careful to use fslswapdim since it may result in an unintended left-right flipping. It's better to use fslreorient2std. 2. The tool dt-recon computes the coregistration of the lowb volume to the anatomical volume, see register.dat. You can then use the following to coregister FA: mri_vol2vol --reg register.dat --mov fa.nii --o fa-ana.nii -targ subject/mri/T1.mgz where "subject" is the output folder generated by the recon-all command. You should not forget to set the global variable SUBJECTS_DIR Cheers, Ed On 14 Oct, 2011, at 18:00, freesurfer-requ...@nmr.mgh.harvard.edu wrote: Dear Bruce and Anastasia, Thanks for the quick reply!

[Freesurfer] Error with recon-all
Hi, I'm using the version of recon-all that Nick provided at April 17 to be able to run nu_correct prior to the Talairach stage. (I'm on a Mac, OSX 10.6, version v5.1.0). The command given was recon-all -autorecon-all -hippo-subfileds -no-wsgcaatlas \ -clean-tal -s subject. recon-all stopped and issued the following error: cp: ../surf/lh.orig_corrected: No such file or directory. Note that I included the option -no-wsgcaatlas to get a better skullstripping because in the default mode the skulltripping was bad. With this option it looks good. I got the above error regularly for other subjects as well and by including the -no-wsgcaatlas option recon-all finished without error, except for the present case.

Re: [Freesurfer] Error with recon-all
Hi Nick, Apologies, I should have looked at the recon-all.log file myself. It says that there was an error with mris_topo_fixer: it couldn't allocate memory (malloc error). So I guess that the brainmask is still not correct. I will try to fix that with the option -wsmore.

[Freesurfer] Bad pial surface - continued
Hi, I've mailed this once before and tried to solve a persistent problem. Reviewing the results of recon-all I noticed that the derived pial surface chopped away an unacceptable amount of gm voxels. First of all I tried to manually edit some wm voxels, however with no success. Then I tried another solution by combining the FSL-FAST wm segmentation with wm.mgz because I noticed that FSL_FAST produced better results. Although the results did improve, still the pial surface was incorrect. The last option I tried was another set of parameters for nu_correct. Because it concerns 3T scans I used --proto-iters1000 and --distance 50 (see paper of Zheng et al, NeuroImage 48, 73-83 (2009)) and previous e-mails on this subject ("nu-correct parameters", 27 April 2010). Also with these settings the pial surface chopped away too many voxels. I'm desperate, the manuals provide no options on how to fix such problems. The pial surface can be corrected by only REMOVING voxels that are included erroneously but there is no way to extent the pial surface by ADDING voxels.

[Freesurfer] Which volumes to use

Re: [Freesurfer] Total GM and WM volumes
Hi Allison, Thanks. It is still confusing: for the gm the aseg.stats lists cortical as well as subcortical and the total volumes (being the sum of both). But for wm only cortical volumes are present.

Dear Isabelle, In the System Preferences -> Keyboard & Mouse you should select the buttons as follows: left one: primary button, right one: secondary button top on: Button 3 You will now have a 3-button mouse that works fine with FreeeSurfer. Ed Hello, Just getting started with Freesurfer. I'm hoping someone can recommend a 3-button mouse that works well with Freesurfer, on a Macintosh. I purchased a Logitech wireless mouse, but can't get it to work properly. Freesurfer does not seem to recognize the 2nd and 3rd buttons as any different than the 1st/ left button. So I cannot get edits to work, for example, when trying to edit white matter. Any tips appreciated. -Isabelle - Isabelle M.

Re: [Freesurfer] Total GM and WM volumes
Hi Doug, This thread about GM and WM volumes was initiated by my question on how to get the total cerebral GM and WM volumes. From what I understand now is that for the GM I should take the volume named "TotalGray" in the aseg.stats file. In the example below that would be 710389.282729. However, for the total cerebral WM volume I can't use the aseg.stats file because the measure "CorticalWhiteMatter" is ony the cortical white matter volume and does not include the subcortical white matter. Instead I should compute it by means of mris_volume lh.white + rh.white. Is that right? The alternative would be to derive the subcortical white matter volume from one of the stats files and add it to the cortical white matter. Is that possible and if so, how?

Hi Doug, I'm sorry about using the term "subcortical white matter". It was due to misunderstanding your response, viz.
