Dear Nick and Uri, Thank you for your replies, I'm not really into parallel processing and forgive me if I talk nonsense :). From your stories I sketch the following possible scenarios: 1. We use a sort of batch system. For instance, a Linux bash script with 10 recon-all commands or with 10 FSL

[Freesurfer] mri_surf2surf resampling error

Hello there, I'm trying to resample some thickness difference maps using mri_surf2surf. Unfortunately, I keep getting the following error: --- [engram:Multispect] (nmr-std-env) mri_surf2surf --srcsubject 002_MEF_A \ --sval $S

The source type is not curv but paint, so use --src_type paint. Even better would be to use mgh, ie, create lh.thickness_diff as an mgh instead of w (ie, lh.thickness_diff.mgh). And then spec the output to be mgh as well. If you use mgh, then there is no need to spec the format. The paint format

you can save individual labels by selecting the annotation unit you want and saving it, or you can do them all using mri_annotation2label. The vertices should be identical across the various surfaces as they all have the same topology (except the *.nofix ones) On Thu, 7 Dec 2006, Tao Song wr

I'll leave this for Doug. As for the label file, each annotation would be in a different one, but I don't think it will match since there are unknowns in the annotation and I don't think they go to a label file (do they Doug?) On Thu, 7 Dec 2006, T. Song wrote: Thanks a lot, Bruce. Another qu

[Freesurfer] corpus callosum

2006-12-07 Thread Durastanti, Valentina (NIH/NINDS) [F]
Hi, I have two questions: 1. I was wondering if the values of corpus callosum are useful 2. Why the values of the corpus callosum are included in the gray matter data (.aparc.stat)? I need the volume/area of the corpus callosum and I don't understand if the volume given by the stat file is the who

Hi Valentina, If you are referring to the corpus callosum value from the *h.aparc.annot, this region and the values associated with it are not accurate. Our motivation in including the corpus callosum as a region of interest within our gray matter parcellation atlas was simply as an anatomic p

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 We have a SUN grid system at UCSF. I have some shell scripts for using freesurfer on this type of grid. As said earlier, freesurfer does not contain multi-threaded programs. Use of the grid is simply to run multiple instances of freesurfer programs

Andries, You are on-track with the first scenario. If you have the technical skills and time to install the Sun Grid Engine, or PBS (which does nearly the same thing), then the batch interface will be easy for others to submit as many 'recon-all' instances as they want and will handle balancing.
