All, It is noticed that Galaxy/GATK indexes reference fasta & dbSNP file everytime when it runs. Re-indexing takes time (~10min), hence it affects overall run time when it use for multiple times. However, this could be avoided by reusing the available index. Here is the snapshot of the log: INFO 11:43:57,365 HelpFormatter - The Genome Analysis Toolkit (GATK) v1.4-21-g30b937d, Compiled 2012/02/01 19:01:14 INFO 11:43:57,365 HelpFormatter - Copyright (c) 2010 The Broad Institute INFO 11:43:57,365 HelpFormatter - Please view our documentation at http://www.broadinstitute.org/gsa/wiki INFO 11:43:57,366 HelpFormatter - For support, please view our support site at http://getsatisfaction.com/gsa INFO 11:43:57,367 HelpFormatter - --------------------------------------------------------------------------------- INFO 11:43:57,429 GenomeAnalysisEngine - Strictness is STRICT INFO 11:43:57,432 ReferenceDataSource - Index file /tmp/tmp-gatk-6jlUfH/gatk_input.fasta.fai does not exist.
