I am new to running the AutoMR and AutoBuild Wizards, and I am having a problem getting AutoBuild to run. I have run AutoMR and it appeared to run fine, yielding a solution. However, when it did the default hand-off of the MR solution to AutoBuild, AutoBuild crashed. I then tried to run AutoBuild by itself, using the MR solution as the input model. Again, AutoBuild crashed. The error was the same in both cases. I was running AutoMR and AutoBuild from the command line. I am running Phenix version 1.4-3 on an Intel Mac (OS X 10.5.8). The AutoBuild error was **************************************************************************** **** Failed to carry out AutoBuild_build_cycle: child process stderr output: command: 'csh /AutoBuild_run_3_/TEMP0/RUN_FILE_1' sort: invalid option -- 4 Try `sort --help' for more information. **************************************************************************** **** I tried the suggested "sort --help", but at least to me it wasn't helpful. I am guessing that I have some incompatibility with my local installation of "sort" and Phenix? Any help is appreciated. Thanks, Tim
