Hi all
I'm running a group Feat using the latest version FSL(FSL3.2) and FSL3.1.
1. FSL3.2
-Four sessions per one subject.
-Single slice.
I know FAQ #47, but it has to require the following setting.
-add '-2D' to the flirt commands in featreqapply and feat.tcl. (Registration works fine.)
-standard image is my own single slice high resolution image.
In my higher-level analysis(Single-Group Average, One-Sample
T-Test) on FSL3.2, I got many flame's WARNINGs.
###
WARNING: FLAME stage 2 has given an abnormally large difference to stage 1
x=73,y=96,z=0
vox=319
zts[0](vox)=5.64006
zemlowerts[0](vox)=2.54789
beta_mean[0](vox)=0.50859
beta_b[0](vox)/beta_c[0](vox)=1.00022e-10
WARNING: FLAME stage 2 has given an abnormally large difference to stage 1

In gsmanager.cc: line 713
abs(zts[0](vox)-zemlowerts[0](vox))>3
Q: These warnings is from this line... what does this line mean?
2. FSL3.1
-The same data as 1 was used.
-As written in FAQ #47, it does not require any special settings.
I didn't get any flame's WARNINGs.
I checked both zstat1.img. The distribution forms of z-score
of the above 2 data are different from each other. (Using
FSL3.2, it seems that the high z-score area is underestimated??)
Q: Am I doing something wrong on FSL3.2?
thanks,
