Hi Doug, hi List,
I got a question regarding the h volumes inside the analysis sub
directories. The content of those file are the regression coefficients
for each voxel (XY planes) for each condition (Z stack). Supposedly
those estimates are corrected for the noise and would make really nice
Hi Doug,
a related question, why do the h volumes show differing values for
voxels at the odd time points, supposedly the residual variance per
condition, while fast_ldsxabfile only returns one value per voxel for
the residual error variance? My expectation is to just have a single
eresvar
Hi Sebastian,
those are scaled to a global mean of 1000 (so you can think of them as
tenths of percents) -- but it's global, not local. Yes, you can divide
the h volume by the h-offset to give you local percent signal change.
This makes me a little uncomfortable because you can get some
The h volume is a little nasty (blame Anders:). If you want the stddev
of the residual error, there should be a rstd.mgh file there. If you
want to know about the h volume, read on.

selxavg-sess creates a directory called bold/analysis in which several
volumes will be stored. One of

Dear Doug et al.,
I'm trying to test mri_label2label because we've observed some strange
results in the download for:
freesurfer-Linux-rh9-stable-pub-v3.0.2
To test the program, I thought it would be sensible to map a label of
one subject onto
The label coords as created by tksurfer should be that of the white
surface, so you're really just changing the coords from that of white to
that of pial. Can you try removing --trgsurf pial from your cmd and see
if the labels are the same?

It probably won't be the same as a cp in any case, as you will go through
some resampling steps.

I think it should be the same. When the source and target subjs are
the same, there should not be any resampling.
