There might be something wrong with the dicom, so first, try to convert the dicom to nii.gz with mri_convert

Hi all, I try to run dt_recon on my dicom files, acquired with a siemens scanner unsing the command from the wiki. The dwi.nii.gz and the dwi-ec.nii.gz as well as the bval and bvec files are generated without problems. Then following error massage is displayed: " .../dwi-ec.nii.gz ... done reading. MatrixReadTxt: could not scan value [1] [1] WARNING: matlab element type is 1853121906, which is not a matrix. could not allocate 811886962 x 1600270640 matrix Cannot allocate memory unsupported matlab format 1918988400 (unknown) Cannot allocate memory" I think the error is right in the beginning of the DTI GLM Fit and tensor construction, I think a matrix is missing. But when I only try to do dt_recon for one subject I am not sure which kind of matrix I should define and how to give the correct matrix in the command line. Does anybody have an idea? I also tried "--init-fsl" because matlab is only recquired for init-spm, but that doesn't work as well. Thanks a lot!! Best regards, Michelle
