GATK

updating from version 1.0.3471 to 1.0.4705

the new version has changed the way it scans the reference sequence. see also Brad Chapman's observation http://friendfeed.com/yokofakun/a0715b86/updated-gatk-it-doesn-t-want-my-reference-genome

for hg18 one must use Homo_sapiens_assembly18.fasta ( http://getsatisfaction.com/gsa/topics/differences_in_gatk_supplied_hg18_reference_file_vs_ucsc )
