Hello,
(I am also posting this to the AFNI listserv to get their perspective as well)
I am analyzing a fast event related design, and the best way for me to understand the analysis is by making two software packages do the same thing. However, despite my best efforts I cannot get the GLM output for both AFNI and FSL to come close. I am wondering if I'm violating some idiosyncrasy of either package making the results divergent.
Details:
preprocessing steps::
motion correction::: 3dvolreg (AFNI)
spatial smoothing::: susan (FSL)
temporal filtering::: 3dbandpass highpass: 0.01 lowpass: 99999 (with the signal mean added back in: [afni.nimh.nih.gov]) (AFNI)
global normalization::: mean signal across run = 10,000 (FSL)
typical output from each GLM uncorrected(?) zstat (see below to see how I got AFNI zstat) file (single subject thresholded at z=2.33).
FSL zstat file= featdir/stats/zstat#.nii.gz
AFNI # of sig voxels=500
FSL # of sig voxels=1000
overlap of AFNI and FSL sig voxels= 80
I used the 4d-volume output from these preprocessing steps and put them into AFNI's 3dDeconvolve/REMLfit and FSL's FEAT.
I added the mean signal back in and globally normalized the signal to 10,000 because FSL's FILM (prewhitening) function appears to expect that scale of intensities. Does 3dDeconvolve/REMLfit have similar assumptions about the input? Do the data need to be scaled or saved as a certain datatype (i.e. float, int, double, etc.)?
Below is the snippet of code I used to run 3dDeconvolve/REMLfit (written in BASH) and the .fsf file passed into feat. I convolved with single gamma function and I made AFNI's gamma function match FSL's gamma function using this thread: (https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind05&L=FSL&D=0&X=20D3C05165200516F9&Y=steve%40fmrib.ox.ac.uk&P=787303).
One thing that I know is different between the GLMs is that I used the temporal derivative in FSL, but I didn't know how to do something similar in AFNI. Additionally, I don't know how FSL accounts for drifts (specifically my impression is that AFNI uses the -polort option to account for drifts, but I don't know how FSL does it).
Thank you for your help!

I change the Tstat output into Zstat using the following command:
3dmerge -1zscore -datum float -prefix Zmap.nii Tmap.nii (http://afni.nimh.nih.gov/afni/community/board/read.php?1,67177,67218)
I DID NOT use the coef file, I used the Tstat file.
