License problem
by Claus Svarer 11 Jun '13

11 Jun '13

Hi We have just updated one of our Linux servers from OpenSuse v. 12.1 to 12.3. After the update we get the following license error message for some of the freesurfer commands: csvarer@hevesy:/usr/local/nru/freesurfer> tkmedit -help -------------------------------------------------------------------------- ERROR: Invalid FreeSurfer license key found in license file /usr/local/nru/freesurfer/license.txt If you are outside the NMR-Martinos Center, go to http://surfer.nmr.mgh.harvard.edu to get a valid license file (it's free). If you are inside the NMR-Martinos Center, make sure to source the standard environment. -------------------------------------------------------------------------- W have another server still running the older OpenSuse version and there it works without any problems. There hasn't been done any changes to the freesurfer installation directory and it is the same shared NFS mounted directory at both servers. Please help us finding out how to correct this problem so we can use Freesurfer again. Thanks for the help Claus Svarer

Dear Freesurfers I am running an autorecon3 to the same subject that Rafa sent you (the name looks different but is exactly the same subject), with the command to fix the ribbon.mgz the autorecon-2 has finished, so I continued with -autorecon3, but now is encountering the following error, this time seems to be something with the seg.mgz. #----------------------------------------- #@# Cortical Parc lh Thu Jun 6 17:01:26 CEST 2013 /root/trabajo/freesurfer/subjects/qsm1_17/scripts mris_ca_label -l ../label/lh.cortex.label -aseg ../mri/aseg.mgz -seed 1234 qsm1_17 lh ../surf/lh.sphere.reg /root/trabajo/freesurfer/average/lh.curvature.buckner40.filled.desikan_killiany.2010-03-25.gcs ../label/lh.aparc.annot setting seed for random number generator to 1234 using ../mri/aseg.mgz aseg volume to correct midline $Id: mris_ca_label.c,v 1.35 2011/03/02 00:04:27 nicks Exp $ $Id: mrisurf.c,v 1.693.2.2 2011/04/27 19:21:05 nicks Exp $ f[113526]->v[1] = 539832625 - out of range! reading atlas from /root/trabajo/freesurfer/average/lh.curvature.buckner40.filled.desikan_killiany.2010-03-25.gcs... reading color table from GCSA file.... average std = 1.0 using min determinant for regularization = 0.011 0 singular and 384 ill-conditioned covariance matrices regularized Linux localhost.localdomain 2.6.9-34.ELsmp #1 SMP Thu Mar 9 06:23:23 GMT 2006 x86_64 x86_64 x86_64 GNU/Linux recon-all -s qsm1_17 exited with ERRORS at Thu Jun 6 17:01:33 CEST 2013 For more details, see the log file /root/trabajo/freesurfer/subjects/qsm1_17/scripts/recon-all.log To report a problem, see http://surfer.nmr.mgh.harvard.edu/fswiki/BugReporting Any ideas how to fix this?

vertices don't match
by Darren Gitelman 11 Jun '13

11 Jun '13

Dear List I am adding to the post on this error from yesterday regarding problems with running qcache. I know this has been posted to the list before, but the suggested fixes and checks don't fix the problem. See the error below (ERROR: number of vertices in /projects/d20277/dek/done/analyzed/3300/surf/lh.volume does not match surface (145332,147148) ERROR: reading curvature file) 1) Running recon-all -s <subjid> -vno-check does not find any problems. It says everything is verified and checks out ok. 2) Running recon-all -s <subjid> -make all returns the message: make: Nothing to be done for `all'. But when I try recon-all -s <subjid> -qcache I get the error on this and several other subjects, but not all subjects. Checking the modification times on some files it looks like the thickness file came after the curv file.

Re: [Freesurfer] Fwd: problem about file format
by huang bs 10 Jun '13

10 Jun '13

Thanks. I now find that, when I copy (or cut) the re-con folder from SUBJECTS_DIR to the shared folder (with XP), it seems that no changes happen - the file format remains the same. But if I restart the Xubuntu, and copy (or cut) this re-con folder from shared folder back to SUBJECTS_DIR, then the file format automatically changes and the re-con results can not be recognized. This is quite odd... I have to move the re-con results to the shared folder because in the Xubuntu FSV5.1.0 virtual hard disk the space is only 10G. So to me now, if I can expand the disk to, say for example, 50G, then at least I don't need to move the re-con results but just save them in SUBJECTS_DIR, and so the file formats will not change.

Hi David, Just put the commands into your .cshrc file (or .bashrc if you're using bash).

Neuroinformatics Database (NIDB) 4.2.0 released
by Greg Book 10 Jun '13

10 Jun '13

This is an announcement that Neuroinformatics Database version 4.2.0 has been released. This version includes many performance enhancements and new features. There is also a demo server available with some sample MR data and the ABIDE dataset hosted for users who want to test the database without needing to install it locally. General features: * store any binary or text data, including MR (any dicom modality), EEG, SNP, video, audio, images, etc. * store assessment/clinical measure values (DSM code, etc, only values, not full assessments) * real-time QC for MR data, with values stored in the database * automatic pipeline processing of any image data, with results stored in the database * query and retrieve any of the above data and dump to local/remote FTP, NFS share, or export in NiDB format * additionally: DICOM receiver, store family pedigree information, store MR behavioral data, download stats, reports New features: * sharing of imaging data between NiDB instances, while maintaining anonymity and eliminating subject duplication * improved pipelines: testing mechanism for new pipelines, creating/editing scripts, and second level pipelines * query performance improved on pipeline results: 4.4 million result values retrieved in 107 seconds. * methods for creating new back-end NiDB modules Download version 4.2.0 in .tar.gz format or VirtualBox VM: http://nidb.sourceforge.net. We'll be presenting at HBM in Seattle next week, so stop by! NiDB is developed by and with support from the Olin Neuropsychiatry Research Center at Hartford Hospital/Institute of Living.

Hello FreeSurfer experts, I recently downloaded and installed FreeSurfer on my Mac computer, but I have a few questions about the startup. 1. When I run FreeSurfer, I get the following.

I seem to be able to run freeview despite these messages, but some others have told me that these messages do not appear on their computers, so I am wondering why they appear. [SiriasBook:/] csirias% freeview 2013-06-10 12:22:57.739 Freeview[1200:303] invalid drawable 2013-06-10 12:22:57.740 Freeview[1200:303] invalid drawable 2013-06-10 12:22:57.754 Freeview[1200:303] invalid drawable 2013-06-10 12:22:57.755 Freeview[1200:303] invalid drawable 2013-06-10 12:22:57.768 Freeview[1200:303] invalid drawable 2013-06-10 12:22:57.769 Freeview[1200:303] invalid drawable 2013-06-10 12:22:57.781 Freeview[1200:303] invalid drawable 2013-06-10 12:22:57.782 Freeview[1200:303] invalid drawable 3. And my last question. How do I run FreeSurfer automatically when I open the terminal window? I would like to just type 'freeview' into the command line to have the program run, but I currently have to type setenv FREESURFER_HOME Applications/freesurfer/ followed by source Applications/freesurfer/SetUpFreeSurfer.csh in order for the program to run. Thank you so much for any help you can give! Like I said, the program appears to run normally despite the messages, but I just want to know why they are appearing. The last question is more of a convenience issue. Thanks, David
