Greetings,

Based on the error report, my first guess is that 'lf' was not defined prior to calling LFCompute. Typical usage would look like this:

Code:

Read some data
Define some trees and models

LikelihoodFunction lf = (myData, myTree);
LFCompute (lf,LF_START_COMPUTE);
LFCompute (lf,res);
LFCompute (lf,LF_DONE_COMPUTE);

 

Would you mind pasting in the complete code example which leads to the error?

Cheers,
Sergei
