summing across FIR timepoints
by Ellen Lau 12 Apr '12

12 Apr '12

Hi, We ran a first-level FIR analysis on our functional data with selxavg3-sess, which outputs a single ces.nii file for each subject containing the contrast images for all timepoints. Now we would like to create an image representing the sum of a subset of these images in a time-window of interest (e.g. contrast4s + contrast6s + contrast8s) and then bring this single 4-8s contrast for each subject forward to the second-level (presumably by concatenating these summed 4-8s images into a single file that mri_glmfit will accept). Could someone advise us on the best way to do these two steps? thanks, Ellen

aseg.mgz
by Steven Thomas Korycinski 12 Apr '12

12 Apr '12

Freesurfer users, Can anyone tell me if the subcortical segmentation shown in TkMedit (aseg.mgz) is subject-specific or a general outline of structure labels in Talairach space for all subjects? Also, are the statistics provided in aseg.stats based directly on the aseg.mgz or something else? Thanks, Steve

changing data structure
by Anthony Dick 12 Apr '12

12 Apr '12

Hello, I am running the rebuild_gca_atlas.csh program and got the following error for seg_edited.mgz, which is the manually defined file imported from a different program outside of freesurfer. mri_ca_train: segmentation file <path>/seg_edited.mgz is not type UCHAR or FLOAT Is there a way to redefine the data structure?

freeview command line generic overlay colormap question
by Heath Pardoe 11 Apr '12

11 Apr '12

Hi all, I have a question about controlling freeview from the command line. I would like to overlay some z-score maps for individual subjects on the fsaverage inflated surface. I would like to use the 'color wheel' color scale setting and threshold the images between -1 and 1 standard deviations (for example). Because I have a number of subjects, I was hoping to make this a bit easier using the command line. So far I use the command: freeview --surface /opt/freesurfer/subjects/fsaverage/surf/lh.inflated:overlay=lh.overlay.mgh:edgethickness=0 --screenshot lh.overlay.png But I can't figure out from 'freeview --help' how to control the color of the overlay and the thresholding levels. Does anyone know if it is possible to control these options from the command line? Or an alternative approach, maybe using tksurfer or even slicer? Best wishes Heath

mri_segstats memory corruption error

Hello FreeSurfers, I ran the following command: mri_glmfit-sim --glmdir rhFwhm12Sig13 --sim mc-z 10000 1.3 mc-z.abs.13.jls --sim-sign abs --overwrite When it gets to the part to do mri_segstats, it throws this error: 0 1*** glibc detected *** mri_segstats: malloc(): memory corruption: 0x2f302488 *** I see this person had a similar problem: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg15423.html All of my other mri_glmfit-sim commands have worked fine. Is this a bug in mri_segstats? I am rerunning it again to see if it is duplicatable.

Clarification on centos version/updates/patches
by Irwin, William 11 Apr '12

11 Apr '12

Hi- It would appear the stable release for centos6 is ready for primetime 'stable5.1-bin.tgz'; Is this correct? There is an updated version of 'mri_info' based on file size (ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/misc/linux-centos6_x86…) mri_info in 'stable5.1-bin.tgz': 9787048 04-Oct-2011 13:45 mri_info outside of 'stable5.1-bin.tgz': 9866032 04-Oct-2011 11:32 Which version is the most current? Can the contents of 'stable5.1-bin.tgz' be extracted into /freesurfer/bin to overwrite the extant files? Additionally, there is a versioning discrepancy between 'trac-all' located in (http://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/misc/allplatforms/) '$Id: trac-all,v 1.35 2011/09/02 19:19:22 ayendiki Exp $'a and the version packaged with the cenos6_x86_65 'stable5.1-bin.tgz' '$Id: trac-all,v 1.22.2.9 2011/09/02 19:21:03 ayendiki Exp $' I did not comprehensively look for any other discrepancies-these just happened to stand out based on the work I was doing today. Thanks much, Wil
