Hi Sergei, I'm trying to get a branch length between two terminals using

Code:

brLength = BranchLength ( FixTree, "CHB104EN, CHB104" ); 

where CHB104EN and CHB104 are terminal nodes in a topology. However, brLength returns -1. Actually, the code I'm using is

Code:

ExecuteCommands ( "brLength = BranchLength ( FixTree, \"" + PairData[ j ][ 0 ] + "; " + PairData[ j ][ 1 ] + "\" );"); 

where PairData is defined as

Code:

PairData = { { "CHB1EN", "CHB1"}{ "CHB104EN", "CHB104"}{ "CHB106EN", "CHB106"}{ "CHB107EN", "CHB107"}{ "CHB108EN", "CHB108"} } 

I've tried both "," and ";" separated taxa, yet both return -1. Any help/suggestions would be much appreciated. thanks ./w

Hi Sergei, thanks, a space was the problem. regards ./w
