Hi all,
I just loaded raw structural scans into one of my subject directories. They are
of siemens IMA format and I used the following command:
mri_convert -it siemens -ot mgz 001/ 001.mgz
I then got the following error:
reading from 001/...
ERROR: could not parse 001/
ERROR: siemensRead(): 001/
specify one slice in the series and it will find the rest (not the
directory)

Hi Binyam,
I think you need to give it the IMA file name, so something like:
mri_convert -it siemens -ot mgz 001/file.IMA 001.mgz
If that doesn't work there are other options we can try.

thanks Jenni .. I had to change my input file format to siemens_dicom although
they were IMAs. It seems to be working now.

Hi,
Sorry to dredge up an old thread, I was curious about the details on
where randomness is introduced in the following programs (beyond the
normal floating points issues):
> mris_smooth -seed 1234
> mris_sphere -seed 1234
> mris_fix_topology -seed 1234
> mris_ca_label -seed 1234
I assume t
Yea, some siemens scanners/dicom servers produce dicom files with IMA
extensions, which fools our software into thinking it is the old ima
format.

Hello all,
Is there some information on the wiki about the
srctoDst voxel-to-voxel transform and the rastoRAas
transform?

There is this page:

and there, open Doug Greve's PowerPoint file, which describes the
transforms used within Freesurfer.

Hi Bruce:
Is there a way that I can load the MEG timecourse data on the freesurfer
surface? Is it possible that we could get the timecourse waveform for a
specific point on the surface?
Thanks!

sure, if you save it in the right format. The easiest thing to do would
be to save it as a volume, where the 1st spatial dimension is # of
vertices on the surface, and the last (4th one) is the # of time points
(the 2nd and 3rd would both be 1). Or there are other formats you can save
in if you
If the time course is in the proper format, then you can. It needs to
be in one of the "volume" formats, eg mgh or mgh. The number of cols
should equal the number of vertices, the number of rows = # of slices
= 1, and the 4th dim is time.
Then run
tksurfer subject hemi surf -timecourse yourfile
Actually, I think the w file only holds one time point, so that prob
wont work. If you want to go the matlab route, you can do something
like:
mri_convert lh.curv lh.curv.mgh # convert to mgh for a template
then in matalb
f = MRIread('lh.curv.mgh');
f will be a struct
f.vol will be a 4d matr
oops, you're right. Anders wrote another format for multiple time points,
but I can't seem to find it. The volume is the best way to go these
days though.

I would like to calculate total brain volume (defined as: total white,
gray, and subcortical altogether). Should I take the BrainSegVol and
minus out cerebellum and ventricles, or add the white and gray matter

Hi Derin,
the aseg labeling of cortical gm is not that accurate - the surfaces are
quiet a bit more so. We have a new tool for generating the estimate of the
gm and wm volume from the surfaces called mris_volume and mris_wm_volume. I
think Doug or Nick has integrated it into the dev version of
Bruce,
So if I downloaded the dev version of the program I could use it to get
the volumes from subjects processed with 3.0.3? And would adding these
volumes together generate the total volume I'm looking for (including
subcoritical)? Thanks!

you would need to add in whatever subcortical components you wanted to
include, as they are excluded from the wm volume

Hello All,
After making changes using tkregister2 the input
registration matrix changes.IS there an 'optimum'
input registration matrix that i should try to get.I
notice that the closer the values(last column of the
input reg matrix) are to zero the better the outcome.
Thanks in advance.
Chacko.
