FS-FAST "If: Expression Syntax" Error
by Hibert, Matthew Louis 18 Jul '16

18 Jul '16

Hi All, I'm running into an error analyzing some fMRI data with FS-FAST in Freesurfer version 5.3. The analysis runs fine until it gets to the register-sess part, which quits before actually starting to do any registration. The last line of the log file, attached, is "if: Expression syntax", but there are no other errors prior to that. The command I'm using, analysis, and contrasts have all worked on several other similar data sets. Has anyone encountered this problem before, or know what's causing it? Thanks, Matt Clinical Research Coordinator Stufflebeam Lab Athinoula A. Martinos Center Massachusetts General Hospital 149 13th Street, Room 1115S Charlestown, MA 02129

Question about NULL event with Optseq2
by Feng Zhou 18 Jul '16

18 Jul '16

Dear experts, I'd like to use optseq2 to optimize the order of events as well as inter stimulus intervals. My experiment contains 3 runs and each run contains 3 events, say Cp, Cn and Pobe events Each stimulu will be presented 4, 4 and 1 sec and the numbers of times that each event type will be presented during the course of the run are 12 12 and 4 respectively, and interstimulus interval ranges from 8–12 sec. So each run would last around 380 sec. I used the following code: optseq2 --ntp 380 --tr 1 --psdwin 0 20 1 --ev Cp 4 12 --ev Cn 4 12 --ev Prob 1 3 --evc 1 -1 0 --tnullmin 8 --tnullmax 12 --nkeep 3 --o IAPS --nsearch 10000 However, the durations of some NULL events were more than 12 sec and the last NULL events were more than 30 sec. Did I use optseq2 in the right way? How could I fix it? Thanks in advance & Best regards, Feng Zhou

Inquiries about thickness and lgi group analysis
by Mahtab Farahbakhsh 18 Jul '16

18 Jul '16

Dear FreeSurfer, I am doing group analysis for thickness and LGI values. I have just got the output and the output of both analyses (sig.mgh file view in Freeview) are exactly the same. Would you please guide me with this? Best Regards, Mahtab.

Comparing between a group of subject
by Aman Montazeri 18 Jul '16

18 Jul '16

Hi Freesurferes, Sorry for my simple and rookie question, I'm a new user and couldn't find my answer after a bit googling. I have a group of subjects and want to compare their thickness with a baseline (average of my subjects). I thought to use the mri_avarage to make the baseline (Average of all of my subjects), but don't know how to compare them with the baseline after making the baseline. Any help would be highly appreciated Thanks, Aman Ps. I have looked into GLM and longitudinal processing tutorials; GLM doesn't work for me as I don't have any variable to regress against; longitudinal processing is also for comparing different time shots of the same subject (my case are 40 different subjects).

BrainSegVolNotVent
by Eryilmaz, H. Hamdi 18 Jul '16

18 Jul '16

Hello Doug and Freesurfers, I am trying to compute a structural measure called 'BrainSegVolNotVent' as an approximate value of total brain volume. 'BrainSegVolNotVent' is now present in aseg.stats files but the dataset I'm working on was preprocessed using FS 5.0, which did not produce this variable. Per your advice I found in a previous email, I reran mri_segstats adding the flags --brainmask mri/brainmask.mgz --brain-vol-from-seg. The new aseg.stats file contains the following lines that were added after running this command: # Measure BrainMask, BrainMaskNVox, Number of Brain Mask Voxels, 1667093, unitless # Measure BrainMask, BrainMaskVol, Brain Mask Volume, 1667093.000000, mm^3 # Measure BrainSegNotVent, BrainSegVolNotVent, Brain Segmentation Volume Without Ventricles, 232145.000000, mm^3 # Measure BrainSeg, BrainSegNVox, Number of Brain Segmentation Voxels, 1410666, unitless # Measure BrainSeg, BrainSegVol, Brain Segmentation Volume, 1410666.000000, mm^3 The numbers look a bit odd. BrainSegVol and BrainSegVolNotVent should normally be close to each other, right? Also unitless values such as BrainSegNVox and BrainMaskNVox seem to be equal to their corresponding volumetric values. Do you have any idea what might have gone wrong? Here's the command I ran: mri_segstats --seg mri/aseg.mgz --sum stats/aseg.stats --pv mri/norm.mgz --empty --excludeid 0 --excl-ctxgmwm --supratent --subcortgray --in mri/norm.mgz --in-intensity-name norm --in-intensity-units MR --etiv --surf-wm-vol --surf-ctx-vol --totalgray --ctab /usr/local/freesurfer/stable5_0_0/ASegStatsLUT.txt --subject SUBJECT_ID --brainmask mri/brainmask.mgz --brain-vol-from-seg Thanks very much for your help! Best, Hamdi

registering to fsaverage
by Trisanna Sprung-Much 18 Jul '16

18 Jul '16

Hi there So I have sulcal labels from another software (.mnc format) from which I am trying to generate some probability maps. I was able to convert the .mnc to .mgz surface overlay using mri_vol2surf for my MRIs after running all MRIs in recon-all. So, now I have all my painted voxels as surface overlays, as I was instructed to do a few months ago. I was told that the next step would be to use mri_surf2surf to resample the overlays to fsaverage. I am a bit confused as I would think that the next step would be to take the surface overlays and inflate them before I register them to fsaverage. I see that when recon-all runs, it computes the registration of the MRI surface to fsaverage and saves it as sphere.reg. *Is there a way I can inflate my surface overlays in a similar manner and then apply this same registration to my surface overlays?* Or am I missing something? thanks very much!

mri_convert WARNING: files are not found to be different and cannot be sorted
by Olivia Walton Stanley 18 Jul '16

18 Jul '16

Hello all, I have run mri_convert on a series of dicoms and received the following error for several of my images. As with the previous bug report for this I have run mri_info on my dicom series and it’s output is below. My main concern is since these dicoms are being jumbled up and I am not sure what that warning means. Is it the dicom header it is comparing? Can you elaborate or put me on track to debug this error? Thanks, Olivia mri_info is below: mri_info 500/Image_SLC0_CON0_PHS0_REP1_SET0_AVE0_2.dcm Getting Series No Scanning Directory INFO: Found 9218 files in 500 INFO: Scanning for Series Number 3076 INFO: found 4608 files in series INFO: loading series header info.

Regarding: Concatenating hippocampal to generate sig.mgh
by Dr Sampada Sinha 18 Jul '16

18 Jul '16

Dear freesurfer experts, Will you please let me know if it's possible to get one average mgz image file by concatenating the hippocampal volumes of different subjects using dev version? Since, I already have the hippocampal subfields mgz volume files, I intend to run the glmfit later on between two groups to get sig.mgh files. Thanks and regards?
