Hi Russell, I'm sorry for the trouble! I wonder if you could try these things: 1. run this test: phenix_regression.wizards.test_command_line_misc test_erraser Does that run? 2. Have a look in your directories: /home/Russ/Desktop/erraser_test/precursor_chi_erraser_temp/... looking for the files minimize_1.out and minimize_1.err. Do they give you any useful information? If neither of these helps, please feel free to email me directly at [email protected]. The next thing to try will be to run the command that is listed at the end of your email directly (you may need to be in the right directory for it to run though...this will be the directory where minimize_0.pdb is located). All the best, Tom T ________________________________ From: [email protected] [[email protected]] on behalf of Russell Chan [[email protected]] Sent: Thursday, November 29, 2012 3:33 PM To: [email protected] Subject: [phenixbb] phenix.erraser error Hi, I'm currently trying to use the new command, phenix.erraser, to refine my RNA structure. I generated a ccp4 map and removed the R-free flags, however it generates an error after its starts its first round of minimization.
