# Single CPU version of Juicer.
#
# Alignment script. Sets the reference genome and genome ID based on the input
# arguments (default human, MboI). Optional arguments are description for 
# stats file, using the short read aligner, read end (to align one read end 
# using short read aligner), stage to relaunch at, paths to various files if 
# needed, path to scripts directory, and the top-level directory (default 
# current directory). In lieu of setting the genome ID, you can instead set the
# reference sequence and the chrom.sizes file path, but the directory 
# containing the reference sequence must also contain the BWA index files.
#
# Aligns the fastq files, sorts, and merges.
#
# If all is successful, takes the final merged file, removes name duplicates,
# removes PCR duplicates, and creates the hic job and stats job.  Final
# product will be hic file and stats file in the aligned directory.
#                                                                       
# [topDir]/fastq  - Should contain the fastq files. This code assumes that
#                   there is an "_R" in the appropriate files, i.e. *_R*.fastq
# From the top-level directory, the following two directories are created:
#                                                                              
# [topDir]/splits  - Where to write the scratch split files (fastq files and
#                    intermediate SAM files). This can be deleted after 
#                    execution.
# [topDir]/aligned - Where to write the final output files.
#
# The following globals should be set correctly before proceeding:
#
# read1str  - portion of fastq filename that indicates this is the "read 1"
#             file; used to loop over only the read 1 and within that loop,
#             also align read 2 and merge.  If this is not set correctly,
#             script will not work. The error will often manifest itself
#             through a "*" in the name because the wildcard was not able to
#             match any files with the read1str.   
#set -e ## This is causing problems; need better error detection
