Invalid Key Error for Freesurfer 5.1
by An Lijun 29 Aug '19

29 Aug '19

External Email - Use Caution Dear Freesurfer experts, Right now I am trying to use Freesurfer 5.1.0. But the software showed ERROR “Invalid FreeSurfer license key found in license file”. We tried to apply license online, however, the license provided online is now for 6.0.0 version and it seems not applicable for 5.1.0 since I still got the same error message as before. May I ask how to get the licnese of 5.1.0? The tricky part is the format of lecense now I get from Fresssurfer is different from the old one in Freesurfer 5.1. New License I get(call license.txt): xxxxxxxx(a)gmail.com<mailto:xxxxxxxx@gmail.com> 43508 *CRBDdLNbgmws FSOkaDD5AxOQk Old License(call .license): xxxxxxxx(a)gmail.com<mailto:xxxxxxxx@gmail.com> 39689 *1 PS: I tried to use `dos2unix` to transfer the license to unix format, but it seems no help. Thanks for your help! ------------------------------------------------------------------------------------------------------------------------------------------ Best Regards, An Lijun

Time course thalamic subregions
by stdp82＠virgilio.it 28 Aug '19

28 Aug '19

External Email - Use Caution Hi list, I would like to extract fMRI time series from the thalamic subregions that I obtained by the recent tool implemented in FS. I have run mri_segstats --seg subj/mri/ThalamicNuclei.v10.T1.mgz --ctab $FREESURFER_HOME/FreeSurferColorLUT.txt --i subj/rest/001/fmcpr.sm6.mni305.2mm.nii.gz --avgwf Time_Seriesfolder/ADNI011_HC.MNI --id 8120 --id 8121 --id 8122 --id 8123 --id 8220 --id 8221 --id 8222 --id 8223 The command produces this error: ERROR: dimension mismatch between input volume and seg input 76 76 93 seg 169 105 118 Please, I have other questions for you. 1) At starting, I have used the command line reported below: preproc-sess -sf sessid -fwhm 6 -surface fsaverage lhrh -mni305 -fsd rest -per-run -sliceorder odd The -mni305-1mm could be more useful? My raw-data are: data_type UINT16 dim1 64 dim2 64 dim3 48 dim4 140 datatype 512 pixdim1 3.312500 pixdim2 3.312500 pixdim3 3.312500 pixdim4 3.000000 cal_max 0.0000 cal_min 0.0000 file_type NIFTI-1+ 2) In the mri_segstats the input is subj/rest/001/fmcpr.sm6.mni305.2mm.nii.gz. Do you agree? Conversely, should I use the .odd like fmcpr.odd.sm6.mni305.1mm.nii.gz or fmcpr.odd.sm6.mni305.2mm.nii.gz? 3) If I interested to obtained the time course from a unique region expressing the merging of some thalamic regions (i.e. 8121plus 8122 plus 8123), which is the options that should I added? Thanks, Stefano

Converting a binary overlay file to label
by Nillo, Ryan Michael R 28 Aug '19

28 Aug '19

External Email - Use Caution Hello FreeSurfer users/developers. I manually created a binary overlay file on the pial surface. I am interested in looking at regions outside of this overlay file, so I converted lh.cortex.label to a binary overlay file and took the difference between the two. I want to take this new file and create a label so that I can run mris_anatomical_stats on the new region. How might I do this? Sent from my iPhone

Segmentation fail
by Giovana dos Santos Cover 28 Aug '19

28 Aug '19

External Email - Use Caution Dear Freesurfer experts, I am trying to segment the white and pial matter from my MR images but for some reason, the final segmentation always misses some brain areas. I attached here a nu and brainmask image with the segmentation as an example. The MR image I am using is a MEMPRAGE 0.5mm resolution acquisition from a 3T Siemens TrioTim scanner, possibly with a 64 coil channel. Can you please help me figure out how I could improve the segmentation? I am using the following command: recon-all -autorecon1 -autorecon2 -autorecon3 -s hires_test -hires -i high_res.nii On another note, the full recon-all command takes around four days to finish in an 8GB ram mem computer. I would appreciate if you happen to have any suggestions on how I could run it faster, if this is even possible. Thanks Gio.

bug in freesurfer-dev (T2-specific parameters not passed to second call of mri_make_surfaces)
by Marco Aqil 28 Aug '19

28 Aug '19

External Email - Use Caution Hi, I would like to report a bug in freesurfer-dev. I have encountered this bug in a version downloaded on July 11th, 2019, and again in a version downloaded two days ago (August 20th). In short, it seems that parameters specified via an expert file relevant to T2-assisted pial segmentation, such as -T2_min, are not passed to the second call of mris_make_surfaces (the one actually using T2 data). In Freesurfer 6.0.0, this is not the case, and the T2_min parameter is indeed passed to the second call of mris_make_surfaces (although I note that in 6.0.0, when specifying -nsigma_below via the expert file, both the user-specified value and the standard value are passed to the second call of mris_make_surfaces). See below for more details on the specific freesurfer-dev behavior. Best, Marco Aqil Bug description: T2-specific parameters not passed to second call of mri_make_surfaces in freesurfer-dev Call: recon-all autorecon3? -subjid <subject id> -hires -T2pial -parallel -openmp 15 -expert <expert file path> Expert file content: mris_make_surfaces -T2_min 35 >From the recon-all log, the first call of mris_make_surfaces receives the -T2_min parameter: ---------------- #@# Make Pial Surf lh Mon Aug 19 13:43:02 CEST 2019 <scripts folder path> mris_make_surfaces -save-res -save-target -orig_white white.preaparc -orig_pial white.preaparc -aseg ../mri/aseg.presurf -mgz -T1 brain.finalsurfs -T2_min 35 sub-006 lh ---------------- However, the second call of mris_make_surfaces, which relies on T2 data to refine the pial, does not receive the T2_min parameter, and looks as follows: --------------- #@# Refine Pial Surfs w/ T2/FLAIR Mon Aug 19 14:02:23 CEST 2019 <other T2 pial steps> mris_make_surfaces -save-res -save-target -orig_white white -orig_pial woT2.pial -aseg ../mri/aseg.presurf -nowhite -mgz -T1 brain.finalsurfs -T2 ../mri/T2 -nsigma_above 2 -nsigma_below 5 sub-006 lh --------------- I observed the same behavior when specifying -nsigma_below via the expert file.

Contrast of interaction between covariates in FSGD
by Zhi Li 28 Aug '19

28 Aug '19

External Email - Use Caution Dear Freesurfer experts, May I ask how to understand the contrast of interaction between covariates in the example https://surfer.nmr.mgh.harvard.edu/fswiki/Fsgdf2G2V? The interaction of group x age x weight is: [0 0 1 -1 0 0 0 0 0 0 1 -1] Why the interaction between group and weight should be put in the second row (what does each row mean in the F-contrast matrix)? If there are three levels in the factor one (three groups), I guess the interaction of group x age x weight should be: [0 0 0 1 -1 0 0 0 0 0 0 0 0 1 -1 0 0 0 0 0 0 0 0 0 1 -1 0 0 0 0 0 0 0 0 1 -1] Is this correct? If not how should I set this contrast? In addition, if I would like to know the interaction between age and weight without group, how should I set the contrast then? Looking forward to your kind suggestions. Thanks and best wishes, Lizhi

freeview crash -- petsc error when opening volume
by TRISTAN J PAUTSCH 27 Aug '19

27 Aug '19

External Email - Use Caution Greetings all, I'll try to keep this succinct. I'm attempting to deploy FreeSurfer on Ubuntu 18.04 servers here at the lab. I used the stable 6.0/CentOS 6 download, in addition to the dev version of freeview per the .../fswiki/UpdateFreeview instructions. All dependencies have ostensibly been satisfied, all libs from 'ldd freeview.bin' installed. Freeview launches fine and stays open when launched alone, however attempting to open a volume (either through the GUI or directly via the CLI) causes a crash and the following error about 5-8 seconds after launching (brain images begin to populate, then crash): --- [0]PETSC ERROR: ------------------------------------------------------------------------ [0]PETSC ERROR: Caught signal number 11 SEGV: Segmentation Violation, probably memory access out of range [0]PETSC ERROR: Try option -start_in_debugger or -on_error_attach_debugger [0]PETSC ERROR: or see http://www.mcs.anl.gov/petsc/petsc-as/documentation/troubleshooting.html#Si… ERROR: or try http://valgrind.org on linux or man libgmalloc on Apple to find memory corruption errors [0]PETSC ERROR: configure using --with-debugging=yes, recompile, link, and run [0]PETSC ERROR: to get more information on the crash.
