Re: [Freesurfer] sim ocn clusters mean effect size
by Kayle Sawyer 28 Oct '13

28 Oct '13

Hi all, I would like to calculate the 95% confidence interval of the slope for a thickness cluster (vs age in years) produced by mri_glmfit-sim. I have obtained values for my clusters from gamma.mgh and gammavar.mgh using these two commands: mri_segstats --i gamma.mgh --seg mc-z.th1.3.neg.sig.ocn.mgh --excludeid 0 --sum mc-z.th1.3.neg.sig.ocn.gamma.segstats mri_segstats --i gammavar.mgh --seg mc-z.th1.3.neg.sig.ocn.mgh --excludeid 0 --sum mc-z.th1.3.neg.sig.ocn.gammavar.segstats Next, (for each cluster, within each segstats summary file) I would take the “mean” from gamma, and the “mean” from gammavar, and calculate the positive 95% CI thus: gamma + 1.96*sqrt(gammavar) gamma - 1.96*sqrt(gammavar) Would these two values would give me the 95% confidence interval for the effect of age on that cluster, in mm/year? Thanks, -Kayle

Issue with 5.3.0 nu_correction?
by Natalie Garcia 28 Oct '13

28 Oct '13

Hi all, I've tried running auto-recon with version 5.3.0 (on Mac OSX v10.8.2) and the processing stream seems to fail at the intensity correction point. Not sure if it helps, but when I look at the output from the PBS script, I see "nu_correct: Command not found." Any suggestions on what I might be able to do to fix this? Any help would be greatly appreciated. Natalie -- Natalie V. Garcia Graduate Student, Cognitive Psychology Psychology Department The Pennsylvania State University 423 Moore Building nvg109(a)psu.edu

Freeview

Hi all, I recently updated to FreeSurfer version 5.3.0, and I am now having problems with freeview that I didn't have on the older versions. When I go to "Surfaces" and "Load Labels", it only shows one label at a time. Previously, I could add several labels and all would appear on the Figure. Does anyone know a fix for this? Thanks!

Problem generating volume stats with hippocampal segmentation script
by Erin Walsh 28 Oct '13

28 Oct '13

Hi, I'm experiencing a problem when running the automated hippocampal subfield segmentation script. Unfortunately, I have been unable to determine the cause of the error. After reconstructing all participant data with the -hippo-subfields flag, I ran the "kvlQuantifyHippocampalSubfieldSegmentations.sh" script. The script seems to be working fine, generating subfield values for all participants until the very end when it attempts to generate the stat tables (I think). At this point, I receive the following error: /Applications/freesurfer/bin/kvlQuantifyHippocampalSubfieldSegmentations.sh: line 22: volumeStats_left.txt: Permission denied failed to do kvlQuantifyPosteriorProbabilityImages /Applications/freesurfer/data/GEMS/compressionLookupTable_left.txt I've copied some output and the error message below, including the last participant in our folder it runs through before attempting to generate volume stats. Thanks for any help you can offer!

CVS registration questions
by raij＠nmr.mgh.harvard.edu 28 Oct '13

28 Oct '13

Hi Lilla et al, I am preparing to CVS register 30+ subjects to improve FSL probabilistic tractography alignment across subjects. First, thanks for a really cool tool! Then, I have some questions: 1. mri_cvs_register step1 is spherical registration. However, I have already run FS5.3 recon-all -all for all subjects, which includes spherical registration. Are the recon-all and mri_cvs_register spherical registrations identical? If so, will mri_cvs_register be able to use the previously computed spherical registration (with flags --step2 --step3), or will it need to compute a new spherical registration? Will mri_cvs_register overwrite any of my earlier recon-all results? 2. What are the pros and cons for using one of the following as templates, and which one would you recommend: -Randomly selected individual subject -CVS35 -CVS35_inMNI152 3. When using MNI152_1mm as template, I guess this is a 1 mm resolution image (as $FREESURFER_HOME/subjects/cvs_avg35_inMNI152/mri/T1.mgz seems to be in 1 mm resolution)? Technically, is this the cvs_avg35 image that has been CVS-registered with the MNI152_1mm image? Or is this a FLIRT-type 3D registration from cvs_avg35 to MNI152_1mm without surface information (I guess extracting the surface from MNI152 would be difficult)? 4. I run into the following error in FS stable 5.3 (source /usr/local/freesurfer/nmr-stable53-env): mri_cvs_check --mov $SUBJECT Using the CVS template as registration target. The following files are missing: /usr/local/freesurfer/stable5_3_0/bin/mri_cvs_register.settings.txt You need to find these files or run reconall on the data in order to run mri_cvs_register. Is this file required, or is this a bogus error? 5. Are there parallel processing versions that could be run on the cluster? Thanks!

Re: [Freesurfer] installation trouble - error message subjects directory not recognised
by Z K 28 Oct '13

Sven, Well that certainly is odd that. My guess is that there is some sort of extension that Mac is hiding in the finder window (along the lines of what you were talking about with the text editor). Im also a little concerned about the double '//' that is part of your FREESURFER_HOME environment variable. That should not be there, although I don't think its necessarily a problem. Please open a terminal and type the following command: 'touch /Applications/freesurfer/.license' That should fix your problem. Let me know if not. Also, please CC the list on these responses so that they can be stored for others to view. -Zeke On 10/24/2013 02:29 PM, muellersvenc wrote: > Hi Zeke, > > the output in both cases is: "no such file or directory". I have attached a screenshot to this email and you can see my freesurfer directory and the .license file at the very top. Is this maybe a problem with creating such a file with the text editor? There is also a file called LICENSE in the directory but this just contains the license agreement. > > I really appreciate you helping me as I am keen on getting freesurfer to work.

Re: [Freesurfer] Incorrect orientations from MRI convert
by Chiu, Bryan (PHTH) 27 Oct '13

27 Oct '13

Hi Douglas, I've looked at the original images in freeview and they follow the correct talairach coordinates. I've run mri_convert again and the files follow the correct talairach coordinates. It appears this may have been a 'one-off' issue. Will update after I autorecon everything. - Bryan
