aparcstats2table - append option
by Horn, Mitchell Jacob 18 Dec '23

18 Dec '23

Hi FS Devs, Would it be possible to add an "append" flag for use with aparcstats2table and asegstats2table? If I understand their usage correctly, each time one of them are run they will create (or overwrite) a new file. Not urgent but would be useful. Thanks, Mitch

Convert Scanner RAS to Vertex RAS
by Eric Tsang 18 Dec '23

18 Dec '23

External Email - Use Caution Dear All, I have great deal of trouble converting scanner RAS to vertex RAS. I have tried a couple of formula (in the following) which had failed to produce accurate coordinate. [tkR tkA tkrS] = [ScannerRAS 1] / (vox2ras * inv(tkrvox2ras))[tkR tkA tkrS] = [ScannerRAS 1] * inv(vox2ras0) Both of these formula produced distorted coordinates. Please help! Thanks,Tim

cannot read nifti-2 files in freesurfer - files ok in AFNI
by Patricia Pais Roldan 15 Dec '23

15 Dec '23

External Email - Use Caution Dear Freesurfer team, I am having problems reading files with nifti-2 header, the error I get is something like "error: No such file or directory; error: niiRead(): bad number of dimensions (31488) in $file*". I get this error with any FS function (e.g., with mri_info $file), so I cannot work with these files in FS at all. The original files were nifti-1 (and readable by FS) but after processing them in AFNI, they were converted to nifti-2 (and now FS cannot read them). I contacted the AFNI team and everything seems to be alright with the files (AFNI functions can work with them and they can be displayed in the AFNI viewer). Does FS have the requirement of files being nifti-1? Thank you very much in advance.

aparcstats2table - IndexError

External Email - Use Caution Hello FreeSurfer Developers, I'm trying to get the cortical thickness values for a list of subjects using aparcstats2table and I'm encountering this error: aparcstats2table --fsgd subjects.test1.fsgd --meas thickness --hemi lh --common-parcs --tablefile lh.aparc.thickness.table SUBJECTS_DIR : /mnt/wsl/PHYSICALDRIVE1/FS_OUTPUTS Traceback (most recent call last): File "/usr/local/freesurfer/7.4.1/python/scripts/aparcstats2table", line 376, in <module> subj_listoftuples = assemble_inputs(options) File "/usr/local/freesurfer/7.4.1/python/scripts/aparcstats2table", line 273, in assemble_inputs if splitline[0].upper() == 'INPUT': IndexError: list index out of range The fsgd file only contains the list of subjects, as illustrated below: GroupDescriptorFile 1 Title subjects.test1 Input 002_S_0295_S13408 Input 002_S_0413_S13893 Input 002_S_0559_S14875 I have successfully executed the same command for an individual subject. For other measurements (surface area, volume) this error also occurs. It's worth noting that the images and files for the subjects and recon-all are stored on an external hard drive that I have mounted on Linux, emulated on Windows. Could this be the source of the problem? I appreciate any assistance you can provide with resolving this issue. Thanks in advance!

Re: [Freesurfer] Longitudinal LME matlab error - Matrix singular or badly scaled
by fsbuild 11 Dec '23

External Email - Use Caution I don’t think there is any GUI or graphical interface with the runtime environment (which does not require a Matlab license).  Neither does it contain the matlab compiler to build matlab executables, etc.  So if you still need to create Matlab executables either with the GUI or from the command line, you would need to have your own site or personal installation of Matlab with a license.  The Matlab runtime environment in freesurfer subsequently allows you to run what has already been built with Matlab. - R.
