Hello All,
We have acquired our anatomical images on a Siemens scanner as multiecho MPRAGE sequence (4 echos), and wish to unpack the runs so we can perform morphometric analysis using FreeSurfer. What is the optimal way to convert the DICOM files so we can use them with FreeSurfer tools? Specifically, what command line do you recommend for dcmunpack?
When running the command: dcmunpack –src dicomdir we get the following output: Found 1 unique series: 6 6 3D_T1_MEMPRAGE 7.27 2530 7 unknown ROW 650 dicomdir/mr_0006-e02/3d_t1_memprage-00533.dcm Not sure how to interpret this.
Thanks.

That tells you there is one "series" in that folder. The series here means a volume, though there are many dicom files. dicomdir/mr_0006-e02/3d_t1_memprage-00533.dcm is just one in the series. To use this, you can run
recon-all -s yoursubject -all -i dicomdir/mr_0006-e02/3d_t1_memprage-00533.dcm
or
mri_convert dicomdir/mr_0006-e02/3d_t1_memprage-00533.dcm output.nii.gz

We ran the following command, but the clarity improved minimally. Therefore, is there another command that you would recommend.
Thanks,
