Problems installing freesurfer on Mac OS X (Darwin)
by Catherine Schevon 11 Nov '04

11 Nov '04

Hi, I have been trying to get freesurfer installed on my Mac, and ran into a problem getting csurf to run. I figured out to put the correct path to tclsh into csurf (it's in /usr/bin, not /bin), but now I get an error message: $ tcsh % source fs_setup Setting up enviroment for FreeSurfer/FS-FAST $ Id: FreeSurferEnv.csh,v 1.3 2003/08/05 19:19:16 kteich Exp $ FREESURFER_HOME /freesurfer FSFAST_HOME /freesurfer/fsfast AFNI_DIR /freesurfer/afni FSL_DIR /freesurfer/fsl SUBJECTS_DIR /freesurfer/subjects WARNING: /freesurfer/afni/Darwin does not exist. WARNING: /freesurfer/fsl/bin does not exist. [mccec-061135:/freesurfer] cschevon% csurf tix not found--setenv problem? % Also, I notice that the "tixwish" command doesn't seem to execute when it's run from csurf, although it does create a window when I run it from the command line. Any suggestions would be most welcome! Cathy

mri_convert orientation problem
by Goldman, Aaron (NIH/NIMH) 11 Nov '04

11 Nov '04

Hi, I'm planning to use mri_convert to convert a large number of analyze images into COR format. To test the orientation, I first ran the command on an image with a pill marking the right side. When I did this, the resulting COR files were reversed in the left-right dimension (in tkmedit, the r coordinates got lower as I moved the cursor towards the side with the pill, and when I ran recon-all stage1, the side with the pill was created as the left-hemisphere surface). What option should I add to the mri_convert command to correct the left & right orientation? Right now, I'm using: mri_convert --in_type analyze subj/mri/orig/file.img subj/mri/orig Thanks, -Aaron- Aaron L.

Preprocessing steps of freesurfer on Macs
by Kushal Koolwal 10 Nov '04

10 Nov '04

Greetings, Let me apologize in advance for bothering you all agian with a technical question, but we seem to have reached an impasse and I am hopeful that you might be able to point us in the correct direction. We are struggling to get freesurfer up and running on Mac OS X, and have encountered difficulties with several of the preprocessing steps as mentioned in the Freesurfer tutorial(the steps for averaging and motion correcting Bert's data). I am wondering if you know anyone who has successfully ported the application to the Mac and that might be willing to suggest a fix or two? Also earlier someone had suggest using mri_motion_correct utility but to my surprise there was no such thing in the Mac installaion of freesurfer. All I could find was mri_motion_correct2 utility but even that didn't work. Can anyone please give proper pointers and directions in this matter. We are in a process of almost setting our lab with Mac so that we can start our work on freesurfer. Thanks Kushal __________________________________ Do you Yahoo!? Check out the new Yahoo!

Re: [Freesurfer] FsFast file conversion/preprocessing
by Margaret Duff 08 Nov '04

08 Nov '04

Hi, so, instead of converting the files, i unpacked them into bshort and it gave me, i think, the right amount of files. then i used the command preproc-sess --sf sessid --df sesspar --fwhm 6. it ran for a while, gave me the sections converting input to afni, motion correcting, and matlab file. after it opens matlab it has the errors saying the mc-sess failed. i am running this from /space/troy. it does create the file fmc.mcdat and it looks like its complete. it just stops after that and doesn't make the actual motion corrected files. thanks for your help. margaret SPM stores each *frame* in a separate file, but all slices for a given frame in the same file. Thus, the number of files will equal the number of frames. bshort/bfloat stores each *slice* in a separate file, but all frames for a given slice in the same file. Thus the number of files will equal the number of slices. Does this resolve the difference? It sounds like your bshorts are not being converted to AFNI properly. Can you send me your preproc-sess command-line and the location you are running it from? doug Margaret Duff wrote: > > Hi, I have 12 runs of functional data I am trying to convert to FSFast > formats and then preprocess.

tksurf doesn't recognise mouse position
by Glenn Lawyer 03 Nov '04

03 Nov '04

Hi, I'm having a problem choosing points with tksurfer. Essentially, it does not register the mouse position. More specifically, when I start the program [badger@dhcp-1017-4 ~/freesurfer]$ tksurfer HU0018 lh inflated The tool/command window shows the cursor vertex index as none and the mouse vertex index as none. When I move the mouse over the display window (no clicking yet!), the mouse vertex index shows 83914. This number does not change, regardless of the position of the mouse. It is not a latency issue, as even after a full minute, nothing has registered. Note that the cursor vertex still shows "none". Now I left-click with the mouse. The cursor index shows 83914, and a blue star appears on the image at that location REGARDLESS of mouse position when I click. I move the mouse, and click with the mouse, but the mouse and cursor vertexes do not change. If I manually edit the cursor vertex index, I can move the blue star. Oddly, if I right-click on the image, it re-draws. So at some level mouse events are getting through. Also, tkmedit seems to work, at least the mouse and cursor values update as I scroll around the image. setup: RH9, tk/tcl 8.3, modern machine (2.6 gh pentium 4, 1.5 gigs ram, intel video-on-motherboard) /usr/lib/libtk8.3.so /usr/lib/libtcl8.3.so /usr/lib/libtcl.so /usr/lib/libtclstub8.3.a Ideas, anyone? +glenn -- I want to go farther, farther!

Re: [Freesurfer] tkregister2
by George Papadimitriou 01 Nov '04

01 Nov '04

tkregister2 was used to overlay (i.e. co-register) volume s to volume f. This actually succeeded; you can see results with: % tkregister2 --targ f_000.bfloat --mov s_000.bfloat --reg \ register1.dat Now, I want to actually create an actual new volume (e.g. s_to_f) that is in register with f, using the information contained in register1.dat. For this purpose I used mri_vol2vol, but ended up initially with a "zero volume" and then with a stretched out of version of s that is not in register with f. Does this make sense? Please, let me know if you need me to provide additional info. Thanks a lot! George P.
