I think that I got it. Overall, I am trying to create a source volume conduction model, calculate the lead field matrix, and then create a source model. My instructor said that it might be possible to do this in Freesurfer. Sorry, I am kind of new to
using the terminal. Could you tell me how to go about doing that in this program or direct me to the part of the sit where I can start working on next steps? Or do I need to use another program like FieldTrip for the model? Also what will the format of the
file be after the command is finished?

The recon-all option is no longer working and neither is the other one. I am getting an error.

Hi Isaiah
recon-all -i <input file> -s <subject identifier> -sd <dir to put subject in> -all
should do the trick. <input file> should be a *single* file in the right dicom series, or a .nii file. Don't use analyze

Hello Bruce,
Thanks for the response; I tried the inputs from the check freesurfer page.
I just tried to do the run recon-all and got the list of possible commands.
The input images are unix executable files separately, but I can convert
them to .hdr/.img or .nii using mricron. They are MRI images. How do I
direct these files to the command? And this is the command to do the things
I previously asked, right?
Isaiah
Hi Isaiah,
what are the input images that you have? What format and what
imaging
sequence? You should be able to just run recon-all on them
(check out
recon-all -help)
cheers

Hello All,
I was testing to see if the freesurfer program works
and it does seem to work for anything besides the
free viewer program. I do not know what is wrong
with the others; do you have any ideas? Also I am
trying to use the inhomogeneity correction, convert
the images that I have to 1x1x1 ratio, arrange the
directions of the image, and save the program in
analyze format. If possible could you outline that
process or give me a link that will direct me on the
process? Thank you. Your help is really appreciated.
Isaiah Smith
