Sherpa_1.4.3 data file ct10.00.pdf cannot be opened

[Generic User (don't modify these fields)]

I installed Sherpa 1.4.3 on Fermilab machines (running scientific linux 5) with gcc 4.6.2.

The simple installation

./configure; make; make install; 

went through without any issue.

However, when I try to test one of the examples, say Examples/LHC_SingleTop, and do ../../bin/Sherpa

an error is displayed and Sherpa terminates:

Initialized the beams Monochromatic*Monochromatic
  Data file ct10.00.pds                              cannot be opened in SetCT10!!

The same procedure runs fine without any issue on my laptop.

the error persists when switching to a different pdf For instance, running sherpa with the option PDF_LIBRARY=MSTW08Sherpa PDF_SET=mstw2008nlo

gives me a similar error

Initialized the beams Monochromatic*Monochromatic
Reading PDF grid from /MSTW08Grid/mstw2008nlo.00.dat
Error in c_mstwpdf::c_mstwpdf opening /MSTW08Grid/mstw2008nlo.00.dat

I'm not able to reproduce this on other SL5 machines. Is it possible that your Sherpa installation didn't finish and the ct10.00.pds file has not been installed into <prefix>/share/SHERPA-MC/CT10Grid?

If I may join... If you look at the svn directory tree for the 2.0.b2 release than you can clearly see that not all pdfs that are listed while using SHOW_PDF_SETS are present. For example, for the MSTW08 sets there are 4 PDF sets, while there should be more than 10.

Hi Wojciech,

that's correct, only the "standard" PDF sets (e.g. mstw2008nlo.00.dat, ct10.00.pds which this report was about) are distributed with Sherpa. The other ones are made available in the interface, but the data files have to be downloaded by the user from the PDF's websites (otherwise our tarball would become too large).

Given that I can't reproduce the original problem and there was no feedback from the original reporter I am closing this ticket.

As an alternative, there is always the option to use our LHAPDF interface together with the multitude of PDF sets available in LHAPDF.

Cheers, Frank
