In the TOP_DIR, I have two directories (DTI-1 and DTI-2), each directories has DWI dicom files.

I ran fat_proc_convert_dcm_dwis -indir "./TOP_DIR/DTI-1" -prefix ./TOP_DIR/DTI-1/DWI/dwi1 and
fat_proc_convert_dcm_dwis -indir "./TOP_DIR/DTI-2" -prefix ./TOP_DIR/DTI-1/DWI/dwi2

I obtained
in the ./TOP_DIR/DTI-1/DWI/, dwi1.nii.gz, dwi1_bval.dat, dwi1_cmd.txt, dwi1_cvec.dat, dwi1_matA.dat, dwi1_matT.dat and dwi1_rvec.dat
in the ./TOP_DIR/DTI-2/DWI/, dwi2.nii.gz, dwi2_bval.dat, dwi2_cmd.txt, dwi2_cvec.dat, dwi2_matA.dat, dwi2_matT.dat and dwi2_rvec.dat

now I would like to concatenate two results above into one result, for example,

in the ./TOP_DIR/DTI-con/DWI/, dwi_con.nii.gz, dwi_con_bval.dat, dwi_con_cmd.txt, dwi_con_cvec.dat, dwi_con_matA.dat, dwi_con_matT.dat and dwi_con_rvec.dat


I am still not sure if 1) I need to concatenate them at the DICOM level and do fat_proc_convert_dcm_dwis, or
2) fat_proc_convert_dcm_dwis first and concatenate them ( I mentioned above)?

Also which command or which method can perform this?
