Hi all,

I just upgraded from an older release (2.1.1) to the current version of moses. And I found the regular expression in line 780-781 and in line 1198-1204 of /scripts/ems/support/analysis.perl does not match the .trace and .graph files, respectively.

The .trace file I get is something like this:

Trans Opt 0 [0..12]: [12..12]=</s> [0..11]=S : S ->S -> S </s> :0-0 : term=1-1 : nonterm=0-0 : c=-0.219483 core=(0,-1,1,0,0,0,0,0,0,0) -210.72core=(-100,-22,14,-20.8622,-22.1086,-15.6026,-26.7554,-2.71614,0.999896,-101.045)

the .graph file:

0 40079 S => S -> <s> :: term=0-0 : nonterm=: c=0.110587 core=(0,-1,1,0,0,0,0,0,0,0) [0..0] [total=0.110587] core=(0,-1,1,0,0,0,0,0,0,0)

namely, the original regular expression seems fail to account for the ?term? and ?nonterm? stuff in both cases.

I attempted to fix the problem and I attached the fixed analysis.perl. I no longer get the error output again but I don?t know if it is the right way to do this, so I think it would be nice if some of you can look at that.

Plus, I?m a bit puzzled by the ?old format? and ?new format? indicated in function hs_scan_line. It seems that my experiment is matching to the ?old format?, so is this old one deprecated? How can I switch to the new one?

Thanks!

Regards,
