Hi Doug,
We have an old EPI data set where automatic (preproc-sess) or bbregister with any init type give a bad result. Hence, we are attempting to use a manual register.dat file instead. However, we must be doing something wrong, because changing preproc-sess to use our manual register.dat (done a couple of years ago) seems to have no effect. I suspect our preproc-sess options as not set up correctly. Our goal is to present the results on fsaverage surface.
Our preproc-sess command line is as follows:
preproc-sess -s avml07 -fwhm 5 -surface fsaverage lhrh -per-session -sliceorder siemens -force -fsd bold -noreg -regfile bold/register.dat
The whole analysis script is at
/space/adapt/1/users/tapsya/project_AVISI_avml07/avml07/Analysis_avml07_fsaverage.csh
FS version = 5.1 machine = adapt (analysis running on cluster) setenv SUBJECTS_DIR /space/adapt/1/users/tapsya/subject_MRIs/ individual subject = avml07 surface analysis lhrh, results to be presented on fsaverage surface Total of 3 runs per analysis (each with different number of TRs) Total of categories in mkanalysis-sess = 18 (9 main plus 9 rare target) FIR analysis
Thank you for the advice in advance!
Bests,
Tommi
