Re: [Freesurfer] Revisiting GM ROI list

And, a minor clarification on one of the ROIs in question-- I should have phrase the comment about ROI #80 as follows: 80 non-WM-hypointensities ---> *should be in list of FS_nongm? ... since the name clearly implies that it is non-WM. Basically, I am first wanting to check that the ab

Hi again Eugenio, Sorry for the picky follow-up question regarding the longitudinal hippocampal subfields processing, but do you suggest that when the official version 6 comes out, we rerun everything (including the standard FS long processing) or would it be ok to just rerun the hippocampal

Dear Christian, Both options are OK, as long as you report on your paper how you obtained your results. Rerunning everything with 6.0 has the advantage that the results are easier to reproduce but, if you’ve already QCed large amounts of data processed with 5.3, not rerunning in understandable a

Hi Bruce, Thanks for your answer. What do you think would be better, run recon-all on the original data (with lesions) then edit the aseg for the juxtacortical lesions or use a lesion filling on the T1 and then run recon-all on it. Thanks again. Cheers, Ismail PhD candidate Neurocentre Magendie

Hi Bruce, We re-ran these subjects using recon-all -all -autorecon2-cp -aurorecon3 -subjid freesurferfolder. We got no output files from that, but I'm wondering if freesurfer didn't run only because we incorrectly ran this command with the '-all', or do you think there was some other reason? We

Hi Batool you don't need -all and -autorecon2-cp -aurorecon3 (-all is both of those and more). It must have generated some output. Is there a recon-all.log in the freesurferfolder/scripts dir? cheers Bruce On Mon, 12 Dec 2016, Rizvi, Batool wrote: > > Hi Bruce, > We re-ran these subjects usi

Hi Bruce, I noticed I did it incorrectly, so I started running an hour ago just recon-all -autorecon2-cp -autorecon2 without the -all, about an hour ago. It's starting to generate output now, not sure why it didn't at all last time (may have to do with our new cluster). Will let you know if anyt

Hi Doug et al, I would like to get a different cluster summary stat out of mri_glmfit-sim. Rather than size, I'd like to use the "sum of t-scores" (after Maris & Oostenwald 2007, for example). That is, set a cluster inclusion threshold, and then for each cluster of adjacent vertices that clear the

Hi Doug, Thank you for your note and my apologies for a delayed response. To create the sig.mgh file we used a volume specific mri_glmfit analysis, omitting the --surf flag and using our volume specific input (ces.nii.gz in SIRP_LoadRegression_Stable5.3_012616_sm5_mni305). I don't know if this
