Hi Juegen, there will be a file called something like cache.th20.abs.y.ocn.dat in the glm output directory. This will be a text file with number of columns equal to the number of significant clusters (after correction) and number of rows equal to the number of subjects. The value will be the av

Hi Doug I correlated a behavioural measure with cortical thickness and surface area using mri_preroc, mri_surf2surf and mri_glmfit. Now I would like to extract the individual values of the clusters that correlated with the behavioural measure. Because the individual values should be comparable wi

Use "--sval lh.area". Also, why do you want to smooth it before averaging over the ROI? doug On 06/07/2012 01:29 AM, Jürgen Hänggi wrote: > Hi Doug > > This is my command line: > > mris_anatomical_stats -a area_left_significant_labels.annot -t lh.area > -nsmooth 15 -f $s/stats/lh.aparc.a2005s.sta

Hi Doug This is my command line: mris_anatomical_stats -a area_left_significant_labels.annot -t lh.area -nsmooth 15 -f $s/stats/lh.aparc.a2005s.stats $s lh In the past, you recommended smoothing the data with mri_surf2surf instead of with mris_anatomical_stats. For that purpose, I run the follo

2012-06-06 Thread Jürgen Hänggi
Dear FS experts I have done group comparisons wrt thickness and surface area. The found clusters were written out as annotations, transformed into each individual space, and then the corresponding values were extracted. When using mris_anatomical_stats, values are different for thickness maps dep
