External Email - Use Caution
Dear Kersten: The β1 and β2 in the tutorial model is the regressing coefficients for all the subjects not only for the control subjects because all the intercept are one. I wonder why the reference group is control group in this case?
Thanks in advance.
Best regards, Guodong

External Email - Use CautionDear Freesurfers, I am running resting state analysis. I have TR 2.3, and 209 time points/frames, total length of the scan 483 seconds. I don?t drop any frames from the beginning ( nskip = 0 ).
For one subject, the last two time points are motion outliers. So my tpef file includes numbers 478.4 and 480.7. When I run selxavg3-sess, I get the error time point exlusion file exceed nframes.
I can?t figure out where the bug might be. So once again I would really appreciate your help! Thanks Lauri Tuominen

Hi Lauri, I think this comes down to whether you start counting from 0 or 1. FSFAST starts from 0, so the time of? time point N is N*TR. The maximum you can have is N=208, and so the max time would be 478.4. Your 480.7 exceeds this limit. doug

look in sess01/bold, you should see 001 and 002. Do you?
