Dear PHENIX and ERRASER developers, While ERRASER is running fine (command line) when I use a small PDB file, it fails repeatedly on a complete ribosome model giving following error: Starting erraser Date: Tue May 9 17:53:20 2017 Directory: /home/tofayel/Desktop/test HOSTNAME: localhost.localdomain Log file will be /home/tofayel/Desktop/test/erraser.log Splitting output to /home/tofayel/Desktop/test/erraser.log Running ERRASER Rosetta app... ################################### Path to ERRASER: /usr/local/rosetta_src_2016.32.58837_bundle/tools/ERRASER ERROR: Unique best command line context option match not found for -fixed_res.
