Dear Luli,
Yes; but you need to modify the source code of RelativeRatio.bf. Paste this code:
Code:mxTreeSpec = {5,1};
mxTreeSpec [0] = "tr2c";
mxTreeSpec [1] = "8240";
mxTreeSpec [2] = "10,40,-10,-175,1";
mxTreeSpec [3] = "";
mxTreeSpec [4] = "";
OpenWindow (TREEWINDOW, mxTreeSpec);
internalNodes = BranchCount(tr2c);
leafNodes = TipCount (tr2c);
choiceMatrix = {leafNodes+internalNodes,2};
for (bc=0; bc<leafNodes; bc=bc+1)
{
choiceMatrix[bc][0] = TipName(tr2c,bc);
choiceMatrix[bc][1] = "Taxon " + choiceMatrix[bc][0];
}
for (bc=0; bc<internalNodes; bc=bc+1)
{
choiceMatrix[bc+leafNodes][0] = BranchName(tr2c,bc);
choiceMatrix[bc+leafNodes][1] = "Internal Branch Rooting " + tr2c[bc];
}
ChoiceList (stOption,"Do not constrain:",0,NO_SKIP,choiceMatrix);
if (stOption[0] >= 0)
{
for (k=0; k<Columns (stOption) * Rows (stOption); k=k+1)
{
ExecuteCommands ("ClearConstraints (tr2c."+choiceMatrix[(stOption[k])][0]+");");
}
}
into the RelativeRatio.bf file immediately after
Code:ReplicateConstraint (constraintString,tr2c,tr1c);
The code will prompt you to select one or more branches which you do not wish to constrain with the Relative Ratio test.
Cheers,
Sergei
