Dear Florian,

Sorry to hear that Ample isn't working for you.

I haven't seen this error before, but my initial guess would be that you're 
trying to run Ample on Windows? If so then unfortunately the current release of 
Ample isn't supported on Windows. Most of the work to port Ample to Windows has 
been carried out, and it will be made available in a forthcoming release of 
CCP4, but until then the only solution is to run Ample on Linux or Mac OSX.

If you're not running on Windows, please could you send me (off list) the file 
debug.log, which should have been created in the directory:

/home/flo/crystallography/Virchow/ESRF_20140707/pos7au/ccp4/ROSETTA_MR_0

(the directory may be named ROSETTA_MR_0, ROSETTA_MR_1, ROSETTA_MR_2... etc. 
depending on how many runs you have attempted.)

Just for information, at 197 residues your protein is on the large side 
(although well within the bounds of what Ample is capable of solving), but 120 
models is far fewer then we would normally recommend. The usual recommendation 
is to make at least 1000 models.

Best wishes,

Jens

Subject: [ccp4bb] Ample fails

Dear all,

I'm trying to use Ample from CCP4 (6.4) to solve a structure of 2x197 residues 
from 2.0 A data.
After the generation of initial (120) models by Rosetta (3.3) Ample stops with 
the error-message below.
Could anyone provide me information about the origin of this error and possibly 
how to solve the problem?

Thanks in advance for your replies!

Best wishes,

Florian
