[ccp4bb] phaser 2.3.0 floating point exception

2011-09-06 Thread Petr Leiman
Dear Randy and the Phaser team,

Phaser 2.3.0 brought us several enhancement, but similar to Alexander 
Schiffer's experience, Phaser has failed several times now with a floating 
point exception error at different stages of automated MR: it has stopped in 
the beginning of RF and then in a new run it stopped in the middle of TF. The 
remedy is to explicitly lower the resolution of the input data (that was a 1.2 
A resolution data with a smallish unit cell).  

I can provide the log files and the mtz file if necessary.

Sincerely,

Petr

Dear Petr,

Yes, please do send the log files, MTZ file and anything else needed to run the 
job that shows the problem, so we can track it down.  It's probably best to 
send them off-line.

We couldn't reproduce Alexander's problem, but he tells me that it only occurs 
when the script is started from a mono application (and I confess that I 
don't really know yet what that means).  Once the problem he ran into has been 
defined a bit better, we can look into whether it's something we can fix on our 
end.

Regards,

Randy Read
