Hi there I am installing Freesurfer on a Mac for the workshop next week and I cannot seem to get a license.txt because the page is no longer is accessible. However, it seems to be running fine without this file. Thoughts? Trisanna -- Ph.D. Candidate McGill University Integrated Program in Neuroscience Psychology

Question regarding mri_convert
by Tamara Tavares 23 Sep '16

23 Sep '16

Hi All, I have been using the following command line to convert my dcm/IMA files into a nii files. mri_convert -it dicom xxxxx.dcm xxxx.nii (where xxxx are the name of my files) I realized now that I did not specify the output file type (-ot nii) before the file name. Is this a big concern or are these files still good to use on Freesurfer? In the past, I have toggled between the original volume and the new nii file and everything looks the same. Also, when I have ran it through the standard Freesurfer processing stream, it seems to work fine and there are no errors. Thank you in advance for your help Best, Tamara

[FreeSurfer] aparc.a2009s.stats, MeanCurv, GausCurv
by Hanbyul Cho 22 Sep '16

22 Sep '16

Dear FreeSurfer Team, I heard that the processed subjects/stats/?h.aparc.a2009s.stats included the integrated rectified mean curvature value (MeanCurv) and integrated rectified Gaussian curvature value (GausCurv). I wonder that whether the integrated rectified curvature values are about pial surface or white matter surface. Thank you. Best wishes, Han

freesurfer longitudinal data
by Gabor Perlaki 22 Sep '16

22 Sep '16

Dear all, Is it possible to get simple ROI data (such as aseg.stats or aparc.stats in case of cross-sectional analysis) as the result of the longitudinal analysis, which can be further analyzed by SPSS? Best Regards, Gabor <petzinger.gabor(a)gmail.com>

cluster feature extraction from qdec output
by Damien MARIE 22 Sep '16

22 Sep '16

Dear experts, I would like to know what is the best and simplest way to extract cortical surface area and thickness from clusters obtained after a Monte Carlo correction. This is a group comparison I did with qdec including gender as discrete variable + age and mean thickness or whole hemispheric surface area as nuisance factors, so I would like to get the feature residuals after the removal of the covariate effects. I am sorry, I saw several posts about that but for me it’s not completely clear what command line I should use to get tables for this… Thank you and best, Damien

combining epi dewarping and motion correction w/ mri_vol2vol
by Nathan Tardiff 21 Sep '16

21 Sep '16

Hello, I am attempting to combine my motion correction and b0 unwarping steps. I have .lta files produced by registering every volume of a BOLD run to the first volume using mri_robust_register and a vsmap for dewarping produced by epidewarp.fsl. Is it sufficient to input them both into mri_vol2vol to combine these steps? Something like: The command I was thinking of trying was: mri_vol2vol --mov inFile --targ dstFile --o outFile --lta ltafile --vsm vsmap --cubic Or would something about the creation of the .lta files also need to be changed? Thanks, Nathan
