Hello,

I downloaded ccp4 7.0 linux binary on SUSE Linux Enterprise Server 11 machine (which has no monitor).  AMPLE program when run through command line gives following error

Traceback (most recent call last):

  File "/home1/nkumar/software/ccp4-7.0/bin/ample.py", line 1039, in <module>

    main()

  File "/home1/nkumar/software/ccp4-7.0/bin/ample.py", line 798, in main

    pyrvapi_results.display_results(amopt.d)

  File "/home1/nkumar/software/ccp4-7.0/share/ample/python/pyrvapi_results.py", line 372, in display_results

    major,_,_=ample_util.ccp4_version()

  File "/home1/nkumar/software/ccp4-7.0/share/ample/python/ample_util.py", line 89, in ccp4_version

    return (int(major),int(minor),int(rev.lstrip('0')))

ValueError: invalid literal for int() with base 10: ''

The same version of CCP4 installed using the installer (with GUI) on CentOS 7 64bit machine do not throw any such errors either through GUI (via CCP4i interface) or through commandline.  I am unable to understand the error message.  All the paths in both the machines are correct and other CCP4 programs seems to work fine on commandline on both machines.

Any help is much appreciated,

Thanks in advance,
