====== QA Cluster Example Script ======
The script below is an example script that will run Syam's fMRI QA program, which performs a variety of metrics to assess data quality (SNR, SFNR, center of mass, standard deviations, etc). Naturally, this syntax is courtesy of Syam.


===== my_qsub_qa_script =====
Example usage:
<code>
[user@head ~]$ qsub -v EXPERIMENT=MyExperiment.01 my_qsub_qa_script SUBJNUM</code>

Copy and edit code below:
<code bash runQA.sh>
#!/bin/sh

# This is a BIAC template script for jobs on the cluster
# You have to provide the Experiment on command line  
# when you submit the job the cluster.
#
# >  qsub -v EXPERIMENT=Dummy.01 script.sh args
#
# There are 2 USER sections 
#  1. USER DIRECTIVE: If you want mail notifications when
#     your job is completed or fails you need to set the 
#     correct email address.
#		   
#  2. USER SCRIPT: Add the user script in this section.
#     Within this section you can access your experiment 
#     folder using $EXPERIMENT. All paths are relative to this variable
#     eg: $EXPERIMENT/Data $EXPERIMENT/Analysis	
#     By default all terminal output is routed to the " Analysis "
#     folder under the Experiment directory i.e. $EXPERIMENT/Analysis
#     To change this path, set the OUTDIR variable in this section
#     to another location under your experiment folder
#     eg: OUTDIR=$EXPERIMENT/Analysis/GridOut 	
#     By default on successful completion the job will return 0
#     If you need to set another return code, set the RETURNCODE
#     variable in this section. To avoid conflict with system return 
#     codes, set a RETURNCODE higher than 100.
#     eg: RETURNCODE=110
#     Arguments to the USER SCRIPT are accessible in the usual fashion
#     eg:  $1 $2 $3
# The remaining sections are setup related and don't require
# modifications for most scripts. They are critical for access
# to your data  	 

# --- BEGIN GLOBAL DIRECTIVE -- 
#$ -S /bin/sh

# For fmriqa_generate.pl to run you need to either navigate to your subject's directory or 
# list the file location in the command line below 
# Note that this example lists all required variables in the text below (other than the standard 
# EXPERIMENT=MyExperiment.01), but these could easily be incorporated as arguments
#
# Example:
# qsub -v EXPERIMENT=MyExperiment.01 my_qsub_qa_script
#
# MyExperiment.01 is your experiment (e.g., TestSuite.01) 
# my_qsub_qa_script is your script's full name.

#Perform QA
        SUBJECT=$1
       #SUBJECT="20080505_12345"
	MAINFUNCDIR=${EXPERIMENT}/Data/Func

	cd ${MAINFUNCDIR}/${SUBJECT}

	fmriqa_generate.pl run*/run*.bxh QA

# run*/run*.bxh is the input (this looks for all folders beginning with run, and all the files that match run*.bxh # within those folders)
# QA is the output directory (this will create a QA folder in ${EXPERIMENT}/Data/Func)

# -- END USER SCRIPT -- #
