Brian: Trying out BBMap and I am having problems indexing the reference. My species is Pig which has the following Fasta entry lines in the genome.fa file:

grep '>' ../References/GENOME_DIR/genome.fa
However it appears that BBMap is only creating 6 chromosomes as follows:

Executing align2.BBMap [build=1, overwrite=true, match=long, fastareadlen=500, ref=../References/GENOME_DIR/genome.fa]

BBMap version 31.32
Set OVERWRITE to true
Cigar strings enabled.
Retaining first best site only for ambiguous mappings.
No output file.
Writing reference.
Executing dna.FastaToChromArrays [../References/GENOME_DIR/genome.fa, 1, writeinthread=false, genscaffoldinfo=true, retain, waitforwriting=false, gzip=true, chromc=false, maxlen=536670912, writechroms=true, minscaf=1, midpad=300, startpad=8000, stoppad=8000, nodisk=false]

Set genScaffoldInfo=true
Writing ref/genome/1/chr1.chrom.gz
Writing ref/genome/1/chr2.chrom.gz
Writing ref/genome/1/chr3.chrom.gz
Writing ref/genome/1/chr4.chrom.gz
Writing ref/genome/1/chr5.chrom.gz

Set genome to 1
