lobes volume (WM and GM)
by Gonzalo Rojas Costa 12 Sep '17

12 Sep '17

Hi: I need the complete WM volume for each lobe... not only the WM up to 5mm beneath the lobes (default value) or 20 mm...

QDEC FDR for left and right hemispheres
by Huang, Caleb (NIH/NINDS) [F] 12 Sep '17

12 Sep '17

Hello, When I run FDR on QDEC, I get different p-values for the left and right hemispheres. Is it appropriate to use just one threshold for the sake of consistency? Also, as an unrelated question, is there a way to display the thresholds as p-values rather than log(p)? -Caleb

side effects launching recon-all from matlab system(cmd) call
by Giuseppe Cabras 12 Sep '17

12 Sep '17

Dear freesurfer developers, I call recon-all -all from a matlab script using a system(cmd) which is (apparently) correctly executed, as shown in the recon-all.log (matlab_* attached), i.e.: /usr/local/freesurfer/bin/recon-all -all -cw256 -3T -multistrip -clean-bm -i /home/MRIdata/PUD/31148_MRI_sMRI_400614.nii -s /home/gc/study/recon-all/400614dclass and apparently it run without errors as you can see in the matlab_recon-all.log file, but I get (systematically) a wrong TalAviQA: 0.00000 while, if I run the above bash command directly I get a correct: TalAviQA: 0.97713 as shown in the bash_recon-all.log (attached). I guessed that something wrong happened in talairach_avi --i orig_nu.mgz --xfm transforms/talairach.auto.xfm --atlas 3T18yoSchwartzReactN32_as_orig and the error traced in talairach_avi.log (matlab_* and bash_* attached). In fact matlab_talairach_avi.log is shorter and all imgreg_4dfp end sections are missing which imply that TalAviQA can not be extracted by awk and mritotal transform is performed instead. But really I don't understand why this happens and whether similar issues affects other recon-all subtask using matlab. I double checked this on two linux sistems and with fs version 6.0 and 5.3 ... same results. Thanks in advance for any help, cheers, -- Giuseppe Cabras, PhD - Department of Mathematics, Computer Science and Physics InterUniversity Center for Behavioral Neurosciences University of Udine - via delle Scienze, 206 - 33100 UDINE

FS6.0 on RHEL7 FIPS enabled - ERROR: crypt() returned null with 4-line file
by Sean T. Ma 12 Sep '17

12 Sep '17

Hi FS experts, I ran into a crypt() error while running the `recon-all` on a test brain with Freesurfer 6.0 installed. The server is an FIPS enabled RHEL7. In the `recon-all.log`, the error happened after the `mri_convert.bin` execution: ERROR: crypt() returned null with 4-line file I have attached a snippet below as well as the recon-all.log. Has anyone encountered this error before? I'm suspecting the issue might be due to the enabling of FIPS on RHEL7. I'm having similar OpenSSL prolembs in FSL/FSLeyes. Your input is appreciated!

Hi all, I have finished the command “recon -all” without error. But I get an error that says: “Received X error! Error code :158 Request code : 148 Minor code: 2 Error text :’GLXBadLargeRequest’” I am using the command “tksurfer sub lh inflated”. Then clicking the File->Label->load label.-> and choosing document of “the lh.apare.a2009.annot”. I don’t know why I got this error so would you be able to explain why this is the case and how I can go about resolving this problem? Best, Yvonne

Talairach registration error
by Ariana Vajdi 11 Sep '17

11 Sep '17

Hello, Hope this message finds you well. I was beginning to run recon-all on a dataset and was encountering a problem with the talairach registration. I've encountered this error before here and there, but I've been receiving the same error for every scan that I've been trying to run, and I'm not sure why. It's also the first time I've used NIFTI files as the input - not sure if that's a contributing factor. I've also tried the -use-mritotal flag without any luck. These are the errors I receive: WARNING: neither NIfTI-1 qform or sform are valid WARNING: your volume will probably be incorrectly oriented ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm ***FAILED*** (p=0.0000, pval=0.0000 < threshold=0.0050) Manual Talairach alignment may be necessary, or include the -notal-check flag to skip this test, making sure the -notal-check flag follows -all or -autorecon1 in the command string. I would appreciate your help. Thank you! Warmly, Ariana

Finding Duplicate Subjects in a Database
by Sherrill, John T 11 Sep '17

11 Sep '17

I am trying to find the best way to identify likely duplicate subjects with in a database of about 550 subjects. Some subjects where duel-consented for studies and had multiple scans over a relatively short period of time. What is the best way to tease these out?
