Doubts on bblabel
by Anupa AV 13 Jun '13

13 Jun '13

Dear FS experts, By definition bblabel means.. Applies a bounding box to a label. The bounding box is specified by six coordinates (xmin,xmax,ymin,ymax,zmin,zmax). Only those label points within this box are copied to the output. If a min is not specified, then -infinity is used. If a max is not specified, then +infinity is used. Example: bblabel --l lh.G_cuneus.label --o lh.out.label \ --xmin 0 --ymax -90 --zmin 10 --zmax 20 Keeps label points from lh.G_cuneus.label that have x > 0, y > -90, and z between 10 and 20. The result is stored in lh.out.label. IN THE ABOVE MENTIONED EXAMPLE, WHAT IS THE BASIS FOR THE SELECTION OF X, Y, Z VALUES??

OptSeq2 eff and first order and contrast
by A a 13 Jun '13

13 Jun '13

Hello all, A question regarding the usage of Optseq2 I have this command line optseq2 --ntp 200 --tr 2.5 --psdwin 0 15 2.5 --ev ev20 2.5 20 --ev ev40 2.5 20 --ev ev60 2.5 20 --tnullmin 5 --tnullmax 7.5 --nkeep 1 --o OptSeq_TRIALS/3_null9_6 --nsearch 10000 Now the efficiency tha I get is around 0.5. How I can tell this is a good or bad efficiency ? Is there a comparable level? Also if I would like to test for the first order effect of using a parametric modulation, can I test this using OptSeq2? Lastly, if I would like to test the efficiency of a contrast, say ev60 > ev20, how I do this ? Thanks Adnan

Re: [Freesurfer] License problem
by Nick Jones 13 Jun '13

Regarding any license issue under Opensuse 12.3 and the libcrypt incompatibility. So grab a libcrypt from an older opensuse (one where freesurfer was working, for me, I used libcrypt.so from 11.3, but 12.1 may be a better candidate if it works). Place it somewhere ($FREESURFER_HOME/lib is a good candidate), then add the location to the LD_LIBRARY_PATH environment variable so that freesurfer finds the old libcrypt. There is another workaround but you must contact Nick Schmansky, I don't remember the details. Thanks Nick

"ERROR:: Too many arguments." from recon-all / make_outer_surface
by Tudor Popescu 13 Jun '13

13 Jun '13

Hi all, The command: recon-all -s M19 -localGI resulted in: make_outer_surface('/media/math/all38subj/M19/surf/tmp-mris_compute_lgi-lh.pial/lh.pial.filled.mgz',15,'/media/math/all38subj/M19/surf/tmp-mris_compute_lgi-lh.pial/lh.pial-outer'); exit ================= ERROR:: Too many arguments. I found a previous thread<http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg23414.html>in which someone was getting this error due to a space in the path, but my path doesn't have any spaces or any other dodgy characters. What could the problem be? Thanks. Tudor

Editing masks
by Joshua deSouza 12 Jun '13

12 Jun '13

Hello all, I am having a problem with generating values of the vertices at the hippocampal area. I believe it is a masking issue as reviewing the mask after the glmfit analysis I see that the mask does not cover the entire medial region excluding the corpus callosum. Can I do anything to change the mask as to add deeper brain regions at the hippocampal area? Thank you Joshua

fMRI ROI masks from Brain Voyager QX to FS
by stdp82＠virgilio.it 12 Jun '13

12 Jun '13

Hi list, I performed fMRI analysis by Brain Voyager QX. The masks that describe the fMRI regions of interest are in .vpm and .srf. 1-There is a solution to export these masks obtained by BrainVoyager QX in FS and visualize them on FS surface?2-I'd like to extract from each ROI individuate by fMRI in BX, the cortical thickness values. Is it possible? Thank you very much, Stefano

download error
by Hua, Le - SJHMC 12 Jun '13

Hi, I am currently trying to download the new 5.3 release for macbook lion osx. It downloads fine until about 1.9 GB, then it keeps stalling without giving me any error messages. I have let it continue to run over 20 hours and still no progress beyond 1.9 GB. This occurs with both safari and firefox. The page for 5.2 version is unavailable. Any thoughts or suggestions? Thanks, Le

Re: [Freesurfer] tkmedit on ssh remote machine error
by Z K 12 Jun '13

12 Jun '13

Jon, Here are my findings. -If I ssh from Mac to Linux everything works as expecting, meaning I am running tkmedit on the remote machine but displaying it on the Mac client, and it appears as I would expect. -If I ssh from Mac to Mac I am able to call the tkmedit command but it displays on the server side, not the client. This is definitely some issue relating to X11 (I have X11forwarding set to yes) but I just cant seem to figure it out the exact setting needed to get it to display on the client side. Of course neither of these replicates your error... In your case the image window opens, but the image window is blank (white). If anyone one the list has experienced something similar I would interested to discover what if any remedy exists. -Zeke On 06/11/2013 12:53 PM, Jon Wieser wrote: > thanks zeke > > ----- Original Message ----- > From: "Z K" <zkaufman(a)nmr.mgh.harvard.edu> > To: "Jon Wieser" <wieser(a)uwm.edu> > Cc: "freesurfer" <freesurfer(a)nmr.mgh.harvard.edu> > Sent: Tuesday, June 11, 2013 11:30:50 AM > Subject: Re: [Freesurfer] tkmedit on ssh remote machine error > > Hi Jon, > > I myself have not been able successful running tkmedit over an ssh > session using Mac as both client and server...
