Hello,
I am new to freesurfer. I went through the Wiki and FAQ's but couldn't find information on the format of the input for recon-all. I understand that one of the input files must have a ".dcm" extension.
I have a CD which has MRI scanned images.
The folder structure is E:\DICOM\PA000000\ST000000
under ST000000 there are 8 folders SE000000, SE000001,... SE000008 Each SE00000* folder has files IM000000, IM000001, ...
There are about 180 files all together in the 8 folders.
At first there were no extentions to any of the image files, so, I add an extension ".dcm" to all of the files.
I ran recon-all got an error.
the error.log file has "MRIresample(): source matrix has zero determinant; matrix is:"
Am I on the right path ? or am I missing something ? So I need to convert the images before running the recon ? I see that only 8 files in the first folder in the series are being read, Do I need to input the files in a different structure ?
I am trying to do a proof of concept with our data before buying a machine for running Linux CentOS for freesurfer.
recon-all command generates the following
