[Bioperl-l] get_MLmatrix

This is undoubtably due to changes in the output format between versions.

Aaron and I aren't maintaining this but I am CC-ing the mailing list to see if someone else is working on it.

The roads to solution are 
 - fix the parser
 - run an earlier version of PAML that can be parsed with the current code

Sorry there isn't a better solution but there is no adhered to standard for output by PAML so it requires a developer to constantly track the program and its output and reverse engineer it to keep the parser working. 

For the second error, I am not sure if you are calling the function on right object -- maybe there is a mistake in the documentation relative to the API now, I'm not sure.
The object Bio::Tools::Phylo::PAML::ModelResult has a kappa method so can you check what object type you have when you are calling kappa
e.g.
if you are calling 
$result->kappa
then add debugging print to your code
warn( ref($result), "\n");
