Hi Monks.

[Please refer to Population of HoAoA based on file contents for full context on this. I'm making a new post here, as the previous node seems to have run its course.]

I've been trying (without success) to work out what's going on regarding some error messages I'm getting. I'm getting the following:

Can't call method "isa" on unblessed reference at /usr/local/share/perl/5.14.2/Bio/PopG +en/Statistics.pm line 901, <GEN0> line 182.

..when I run a basic script that passes a whole chromosome file to the Bio::PopGen::Statistics module. I successfully ran this script previously, and got some statistics back, so I can only assume that in re-running it now and getting errors, I must have changed the original program at some point.

When I run my new, larger script in which I used complex data structures to build 100kb windows (that you guys helped me with in the node I linked to above), I get a different error:

Can't call method "isa" without a package or object reference at /usr/local/share/perl/5.14.2/Bio/PopGen/Statistics.pm line 901.

I'd like to know whether these problems originate with my own code, or with the module that the errors are originating from. If it's on my end, what can I do to fix it?

Help as always will be greatly appreciated.
