Hello again,


I have 2 questions about baseline:

1. As far as I understand when you run the 3dDeconvolve with -polort 0, the baseline is estimated with those timepoints unspecified by all the regressors.
My question is how is estimated the baseline when you run 3dDeconvolve with polort default (1)?

======

2. I'm working on an event related analysis and there are 6 conditions in the experimental design. There is no baseline condition (no fixation , no rest). I wonder how is estimated the baseline in this case? Is it a solution to run 3dDeconvolve with polort -1?

=======================

Thank you .
Teodora
