tksurfer - cuvature - thickness
by anthony gallo 06 Apr '06

06 Apr '06

I loaded the curvature -> thickness file.......I don't understand how this gives you thickness measurments. On the surfer interface what are the distance and curvature numbers measured in.....what are the units? What is taken as center for those measurements as well? Thanks very much for your help!

tksurfer script and window resize
by Darren Weber 05 Apr '06

05 Apr '06

Hi Kevin, tksurfer is great, but I need your advice about something bugging me --- maybe you experience it also. I am trying to run a script that flips views and saves out tiff files. I want to do this with a large window, so I have the following near the start of the tcl script: move_window 0 0 resize_window 1000 redraw update UpdateAndRedraw Whenever I call this script for tksurfer, whether using the -tcl option or through tools->Run Script or by source at the tcl command prompt, it runs all the commands in the script after these commands before actually updating the screen position and size. This is despite the 'update' commands. This means that when the commands to rotate the view and save out graphics are actually executed, the window is not the right size. This a real puzzle that bugs me and I can't debug it. I don't fully understand the process model at work here. I can't tell whether this is a tcl, opengl, gnome or kernel scheduling issue (but I think it works in that order). Is this common to all systems or have I got a quirk? I'm running Debian stable (mostly), with nvidia kernel module in a 2.6.8 kernel. Best, Darren -- Darren L.

RE: [Freesurfer] cortical thickness in freesurfer
by Kirk, Gregory 05 Apr '06

While on the subject of cortical thickness. Looking at the new tutorial there is an expanded section on cluster analysis. If my reading is correct the best way to get P values for a study is to do the cluster analysis on the group analysis results and use the P value bounds obtained As a result to publish, etc. This would be a corrected P value if the simulation correction Is used ?

Re: [Freesurfer] mri_watershed: dyld error on OS X 10.3.9
by Xander Meadow 05 Apr '06

Hi Nick, I tried running mri_watershed on Anthony's computer today and got a different error from last time. I got the following error: % freesurfer/bin/mri_watershed dyld: freesurfer/bin/mri_watershed can't open library: /usr/pubsw/packages/gsl/current/lib/libgsl.0.dylib (No such file or directory, errno = 2) Trace/BPT trap So I installed gsl and gsl-shlibs, and I've gotten mri_watershed to work for me. I will have Anthony and then another user try it out to see if installing gsl fixed the issue and let you know. Thank you. >Xander On Apr 4, 2006, at 4:05 PM, Nick Schmansky wrote: > Anthony, > > I don't know what to recommend. I cannot seem to find this symbol > defined anywhere (even Googling it).

mri_watershed: dyld error on OS X 10.3.9
by xmeadow＠uchicago.edu 03 Apr '06

03 Apr '06

Hi, I just downloaded and installed from: http://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer-Darwin-panther- stable-pub-v3.0.1-full.dmg And installed Freesurfer. Most of the apps have worked without a problem, however mri_watershed yields the following error: dyld: mri_watershed Undefined symbols: _acns Trace/BPT trap I have redowndloaded the above package and tried to extract mri_watershed, in case I just got a corrupted binary, but each time I do so I get the same errors. My machine is running MAC OS X 10.3.9. Please let me know if there is any fix I can do for this error? Thank you very much.

working file system and mri_convert of the sample data
by Nam, Euicheol 03 Apr '06

03 Apr '06

Hi, I am practicing freesurfer with the sample data downloaded from freesurfer wiki homepage. I have two questions. 1) My computer doesn't have enough memory capacity, so I saved the data on my USB memory, but I couldn't find how to make freesurfer work with the data in the USB memory drive. Is it possible? According to the tutorial, I have to move the data to FREESUFER_HOME directory of my laptop Linux system. 2) Thus, I moved the sample data to FREESURFER_HOME directory in my computer hard drive but I found another problem in doing mri_convert data. The given sample data was, " buckner_data-tutorial_subjs" I made directory as "mksubjdirs anon" then, cd $FREESURFER_HOME/subjects/buckner_data/tutorial_subjs and setenv {SUBJECTS_DIR} ${PWD} But when I tried to convert files as the tutorial said mri_convert 014-anon/001.dcm ${SUBJECTS_DIR}/anon/mri/orig/001.mgz this command could not be executed and the error message came up "014-anon/001.dcm file or directory does not exist". I guess "anon" directory couldn't have any dcm files because I made the directory in FREESURFER_HOME. And actually I couldn't find any dcm files in the sample data. I'll appreciate if I can get help from you.

Hi, I'm trying to run -autorcon1 of a subject who has 3 mgz images but always came out an error about the motion correction. So I tried run the step using just 1 image and it has gone fine! Have you any suggestion about the reason? The images look good! Thanks Valentina
