version="v0.9 - dd 29/11/2021"
# Notes
# - NOW USES https://github.com/UNFmontreal/Dcm2Bids
# - works for GE/Siemens/Philips
# - wrap around for multiple subjects: use KUL_multisubjects_dcm2bids
export LANG=us.UTF-8
# ----------------------------------- MAIN ---------------------------------------------
# this script defines a few functions:
# - Usage (for information to the novice user)
# - kul_e2cl from KUL_main_functions (for logging)
# - kul_dcmtags (for reading specific parameters from dicom header)
# source general functions
kul_main_dir=$(dirname "$0")

source $kul_main_dir/KUL_main_functions.sh
# $cwd & $log_dir is made in main_functions

cat <<USAGE
`basename $0` converts dicoms to bids format
Usage:
`basename $0` -d dicom_dir -p subject (participant) -c config_file -o bids_dir <OPT_ARGS>
Depends on a config file that defines parameters with sequence information, e.g.
For Philips dicom we need to manually specify the mb and pe_dir:
# Identifier,search-string,fmritask/inteded_for,mb,pe_dir,acq_label
# Structural scans
T1w,T1_PRE
cT1w,T1_Post
FLAIR,3D_FLAIR
T2w,3D_T2
SWI,SWI
MTI,mtc_2dyn
# functional scans

sbref,rsfMRI_SBREF,rest,1,j,singleTE
func,MB_mTE,rest,4,j,multiTE
sbref,mTE_SBREF,rest,4,j,multiTE
func,MB2_hand,HAND,2,j
func,MB2_lip,LIP,2,j
func,MB2_nback,nback,2,j
sbref,MB2_SBREF,HAND nback,1,j
# fmap: 'task' is now 'IntendedFor' (the func images/tasks that the B0_map is used for SDC)
fmap,B0_map,[HAND LIP nback]
# dMRI
dwi,p1_b1200,-,3,j-,b1200
dwi,p2_b0,-,3,j-,b0
dwi,p3_b2500,-,3,j-,b2500
dwi,p4_b2500,-,3,j,rev
# ASL support is very limited (not BIDS compliant for now)
# Indentifier, search-string
ASL,pCASL
explains that the T1w scan should be found by the search string "T1_PRE"
func by rsfMRI, and has multiband_factor 6, and pe_dir = j
the sbref will be used for the tb_fMRI for both tasks (hands and nback)
For Siemens and GE dicom it can be as simple as:
# Identifier,search-string,fmritask/inteded_for,mb,pe_dir,acq_label
# Structural scans
T1w,T1_PRE
cT1w,T1_Post
FLAIR,3D_FLAIR
T2w,3D_T2
# functional scans

sbref,rsfMRI_SBREF,rest,-,-,singleTE
func,MB_mTE,rest,-,-,multiTE
sbref,mTE_SBREF,rest,-,-,multiTE
func,MB2_hand,HAND,-,-
func,MB2_lip,LIP,-,-
func,MB2_nback,nback,-,-
sbref,MB2_SBREF,HAND nback,-,-
# dMRI

# fmap, SWI, MTC and ASL have not been tested on Siemens or GE
Example:
`basename $0` -p pat001 -d pat001.zip -c definitions_of_sequences.txt -o BIDS
Required arguments:
-d: dicom_zip_file (the zip or tar.gz containing all your dicoms, or directory containing dicoms)
-p: participant (anonymised name of the subject in bids convention)
-c: definitions of sequences (T1w=MPRAGE,dwi=seq, etc..., see above)
Optional arguments:
-o: bids directory
-s: session (for longitudinal study with multiple timepoints)
-t: temporary directory (default = /tmp)
-e: copy task-*_events.tsv from config to BIDS dir
-a: further anonymise the subject by using pydeface (takes much longer)
-x: expert mode
-v: verbose
