Hi List, hi Doug,
I just started to use freesurfer 4.5.0 for functional data (before I only used
3.0.5). Now I see that the whole analysis workflow has changed from
mkanalysis-sess.new -> selxavg-sess -> mkcontrast-sess -> stxgrinder-sess to
mkanalyss-sess -> mkcontrast-sess -> selxavg3-sess, now what happens when I
want to add/change contrasts after running selxavg3-sess? Do I still run
stxgrinder-sess or rerun selxavg3-sess (can I avoid recalculating the full GLM)?
And more interesting, I seem to use mkanalysis-sess.new incorrectly as
I get much worse results from the selxavh3 analysis than from the old one. Is
there anything special to take into consideration of non human primate analysis
(I already fix up the gamma function and autocorrelation timewindows to reflect
the use of mion in monkeys). If anyone has a good idea what to try I am all
ears...
best
Sebastian
