External Email - Use Caution Dear Bruce, I had a problem with bringing aseg.mgz into my subject space and you recommend this command before: mri_convert -rl rawavg.mgz -rt nearest aseg.mgz aseg.resliced.mgz which perfectly worked for me but now when I want to try it in new version6 it does not work and the aseg.resliced file contains just corpus callosum!, I don't know which I do wrong because it worked before and still work with the analysis which I done with last version. would you please help me to figure it out?thank you very much for your help. best regards, Nazain PS:the link of previous mail:https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg50794.h…

External Email - Use Caution I was able to circumvent the error by switching from python3 to python2. In python3 print was changed to a function making it necessary to put the arguments in brackets.

correction for multiple comparison: simulation vs grf vs cache
by john Anderson 24 Jan '19

24 Jan '19

External Email - Use Caution Hi Dr Greve, I would like to correct surface based analyses of PET data for multiple comparisons. I ran group comparisons in three spaces. left and right hemispheres and subcortical. I used the method --cache in mri_glmfit-sim to correct the analyses in eft and right hemispheres. I used the method --grf in mri_glmfit-sim to correct the analyses in subcortical regions. My questions are: In one of your kind responses to a collegue here https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2014-January/035650.… you had suggested "If you want to use GRF, you should use smooth by twice the native voxel size. I would not go higher than .01 on the threshold". Would you mind clarify what it means don;t go higher than .01 is this the cwp threshold? also smoothing by twice the native voxel is this means fwhm=2mm? The methods --cache and --grf are giving me the expected results.. when I should consider using simulation --perm ? Thanks for any clarification John

Smoothing before or after PALM (and results conversion for Surf Ice)
by Daniel Leopold 24 Jan '19

24 Jan '19

External Email - Use Caution Hello FS experts and enthusiasts, Thus far, I have used mri_concat to make 4D files of subjects' lh.thickness.fwhm15.fsaverage.mgh files to be used as input for palm. The results maps are of the .mgz format. I can convert these to .nii using mri_convert in order to use fslmaths or fslstats. My dilemma is that I'd like to use another viewing package for the palm results (i.e., Surf Ice) because of its features and some quirks I've encountered while loading results in Freeview. Surf Ice accepts a number of formats ( https://www.nitrc.org/plugins/mwiki/index.php/surfice:MainPage#Supported_Fo…) including Freesurfer's .asc, .srf, .curv, .gcs, .pial, and .w (among *many* others), but I have yet to successfully convert these .mgz maps to a readable format. Surf Ice can read .nii, but loading my mri_converted .nii files results in a uniform surface with 0 at all vertices. Thus, I have two questions: 1) Can you think of a means to convert these surface "volumes" (.mgh/.mgz) to a desired format that can be read by Surf Ice? I've attempted mri_vol2surf, mri_surf2surf, and mris_convert, but cannot find an appropriate format/get things to work. In case it's helpful, readable formats are: 2) My alternative idea would be to instead use mri_concat on subjects' lh.thickness files and later apply fwhm smoothing. Would this approach be feasible? I could test whether pre-palm smoothed and post-palm smoothed results are equivalent, but I'm afraid that the variable dimensions of subjects' native thickness files would cause problems either with palm or when later trying to view the group-level results. Version information: Recon-all run with FreeSurfer 5.3.0 FSL 5.0.8 palm alpha112 Thank you in advance for any suggestions, and please let me know if any additional information would be helpful. With gratitude, Dan

Double cursors when viewing inflated surfaces
by Bunting, Emma 23 Jan '19

23 Jan '19

External Email - Use Caution Hi, When I load my surface overlay (sig.mgh output file from GLM analysis) onto fs average lh inflated surface, I see two cursors when looking at the inner side of the brain. When i click the outer side, only one cursor shows. I have used this command to visualise the data: freeview -f $SUBJECTS_DIR/fsaverage/surf/lh.inflated:annot=aparc.annot:anot_outline=1:overlay=glmdir/matrix/sig.mgh:overlay_threshold=4,5 -viewport 3d I’ve worried that the labels its loading onto the brain aren'’t aligning properly if the cursor is in 2 places. Is there something wrong with my data visualisation command? Thanks in advance, Best wishes, Emma

Version 6.1 and aseg histograms
by Hatton, Sean 22 Jan '19

22 Jan '19

External Email - Use Caution Hi all, Two quick questions: 1. Is there an expected timeframe for when FreeSurfer 6.1 (or next version) is published? 2. In aseg, is there a way to manually select the histograms or mean/SD of the ROIs? Regards, Sean Hatton, PhD Assistant Project Scientist, Center for Multimodal Imaging Genetics UCSD
