MadAnalysis 5

Can't import .lhe.gz

Asked by Antony Martini

When I use ma5 I can import .lhe files to work but it refuses .lhe.gz files with the error:
** ERROR: The dataset '../samples/zz.lhe.gz' has not been found or has a unsupported format.
So I have to unpack manually the .lhe.gz to get the .lhe to run ma5 properly. Nevertheless I think it is possible to directly import .lhe.gz files. How can I fix that?

Thanks.

PS:

dpkg -l | grep zlib :

ii zlib1g 1:1.2.3.4.dfsg-3ubuntu4 compression library - runtime
ii zlib1g-dev 1:1.2.3.4.dfsg-3ubuntu4 compression library - development

When I run ma5, I get this :

So maybe my problem is due to the zlib warning. However zlib is installed in my ubuntu12.04. If I try the 'install zlib' in ma5 it works (it accepts the .lhe.gz format) but after submitting a job I can't use the 'open dir_name/PDF ' and 'open dir_name/DVI' commands anymore since I get the following error:

ma5>open ANALYSIS_0/PDF
ma5>evince: error while loading shared libraries: libz.so.1: failed to map segment from shared object: Permission denied

Hi,

MadAnalysis is not capable to find the zlib headers on your computer. Please check the environment variables.

Cheers,

Benjamin
