+dHCP neonatal dMRI data processing pipeline
+March, 2018
+
+V 0.0.1: Pipeline reflecting the first data release processing
+-----------------------------------------------
+Comprehensive and automated pipeline to consistently analyse neonatal dMRI data from the developing Human Connectome Project (dHCP).
+
+If you use the pipeline in your work, please cite the following article:
+Bastiani, M., Andersson, J., Cordero-Grande, L., Murgasova, M., Hutter, J., Price, A.N., Makropoulos, A., Fitzgibbon, S.P., Hughes, E., Rueckert, D., Victor, S., Rutherford, M., Edwards, A.D., Smith, S., Tournier, J.-D., Hajnal, J.V., Jbabdi, S., Sotiropoulos, S.N. (2018). Automated processing pipeline for neonatal diffusion MRI in the developing Human Connectome Project. NeuroImage. 
+
+
+Installation
+------------
+The pipeline consists of several bash scripts.
+Once it has been downloaded, the first thing to do is fill the correct paths into:
+dHCP_neo_dMRI_setup.sh
+
+The script needs to be run before launching the processing jobs.
+
+
+-------------------------------------------
+Examples
+-------------------------------------------
+To launch the pipeline for a single subject, use the following command:
+${scriptsFolder}/dHCP_neo_dMRI_setJobs.sh ${rawDataFolder}/sub-${cid} ses-${no} ${rawDataFile} ${cid} ${scriptsFolder}/dhcp300_f.txt ${outFolder} ${age} ${birth} ${n_sessions}
+
+This command will submit all the necessary scripts to process the raw dMRI data. The necessary inputs are:
+${rawDataFolder}/sub-${cid}: Path to raw data
+ses-${no}: Session number
+${rawDataFile}: Raw data file name
+${cid}: Connectome ID
+${scriptsFolder}/dhcp300_f.txt: Protocol file
+${outFolder}: Output folder
+${age}: Age at scan (in rounded weeks)
+${birth}: Age at birth (in rounded weeks)
+${n_sessions}: Total number of scanning sessions for the same subject
+
+
+-------------------------------------------
+Non-dHCP data
+-------------------------------------------
+To convert a locally acquired dataset such that it can be used with the pipeline, use the command:
+${scriptsFolder}/utils/getProtocol
+
+By typing the command in a terminal, the necessary inputs will be shown.
+The script will generate a raw data file and a protocol file that can be used with the pipeline.
