Hi all, When running bwa-mem (installed version 0.7.12.1) I get an empty result with the stderr giving the following error: [main] Version: 0.7.12-r1039 [main] CMD: bwa mem -t 1 -v 1 -I 180 localref.fa /home/galaxy/galaxy/database/files/001/dataset_1958.dat /home/galaxy/galaxy/database/files/001/dataset_1961.dat [main] Real time: 12964.149 sec; CPU: 13152.174 sec [bam_sort_core] merging from 50 files... open: No such file or directory [bam_merge_core] fail to open file /home/galaxy/galaxy/database/files/016/dataset_16712.dat.0000 But the files exist and have the .bam extension (i.e. .../016/dataset_16712.dat.000.bam). How can I solve this? Thanks, Cristian
