[Freesurfer] mean cluster surface area in qdec

2013-01-19 Thread xiangbo_2010
Dear Freesurfer Experts, I would like the mean surface area measures of each cluster i found in qdec. I used qdec for a group comparison in surface area between a patient group and a healthy control group. I found 4 different significant clusters (FDR corrected). I would like to extract the mean

Hi Freesurfers, I have two unrelated questions. 1. I want to pre-whiten some functional data without running a GLM on them (we're going to run the GLM in matlab). It looks like fsfast does autocorrelation correction as a part of the selxavg3-sess wrapper. I tried poking around on the wiki and m

Hi Salil - It's a well-known (see email archives) compatibility issue with the newer version of bedpostx, that has different command-line arguments than it used to. You can run bedpostx directly on the command line for now. This is solved in the next version of trac-all. a.y On Sat, 19 Jan

Hi Paul thanks for the clarification, the 178 time points would have been shocking (but pretty cool!). I'll leave this for Martin to answer, although you might try reposting in a week or two if he doesn't since he's trying to finish something and pretty busy. Bruce On Sat, 19 Jan 2013, paul
