Script to upload dicom images for a particular subject session to the tng xnat instance

uploadzip.sh

#!/bin/bash
# uploads dicom images for a particular subject session to the tng xnat instance
# takes five parameters:
# 1: username - xnat username
# 2: password - xnat password
# 3: project - project id
# 4: scan date - session date e.g. '01/02/14'
# 5: directory - the subdirectory that contains the session files
#
# Assumptions!
# 1. The directory name is composed of ${PID}_${SUBJECTNO} and the subject ID can be
# constructed as WH_${SUBJECTNO}.  In this script the PID is assumed to be 11 chars long.
# 2. There is a set of sub-directories under the specified directory each
# corresponding to a separate scan and that the dicom image files are all in
# those scan sub-directories.
# 3. The script is located in the same directory as the session directories
#
# Note that this script zips the dicoms up before sending, instead of sending them all individually
