Hi, I noted there have been a change on the way GATK tools read picard_index.loc, from "tool_data_table_conf.xml": <!-- Location of Picard dict files valid for GATK --> <table name="gatk_picard_indexes" comment_char="#"> <columns>value, dbkey, name, path, tools_valid_for</columns> <file path="tool-data/picard_index.loc" /> </table> And I can't decipher how to use column "tools_valid_for". I was able to show selectable reference genomes in one of the tools by adding its id there, but I don't know how to add the rest. Should I separate them by spaces? commas? tabs?, none of these seem to work for me. Also, what is the best way to identify a tool id, should I just use file name for its xml file? Thanks in advance, Carlos
