+#This is a sample file distributed with Galaxy that enables tools

+#the directories in which those files are stored. The sam_fa_indices.loc
+#file has this format (white space characters are TAB characters):
+#
+#index	<seq>	<location>
+#
+#So, for example, if you had hg18 indexed stored in

+#
+#index	hg18	/depot/data2/galaxy/sam/hg18.fa

+#Your sam_fa_indices.loc file should include an entry per line for

+#index	hg18	/depot/data2/galaxy/sam/hg18.fa
