I encountered a fairly common error from phaser (2.6.1) but I do not know how to fix it. The error message is:

***************************************************************************

The program run with command: /usr/local/src/ccp4-7.0/bin/phaser 

has failed with error message

child killed: segmentation violation

***************************************************************************

I was trying to search for 1 copy of ensemble1 and 4 copies of ensemble2. Alternatively, I also tried search 1 copy of ensemble1 and 4 times 1 copy of ensemble2. And both way yielded this error.

I appreciate your input!

Best,

Chen
