In my fungus, I found diverse intron presence/absence dynamics among different isolates. I have built a tree using exon sequences and want to infer what evolutionary events ever occurred for introns based on the exon tree. That is, how many times of intron loss and how many times of intron gain events were there in the evolutionary history?
I know MacClade should help me, but MacClade never works in newer versions of Mac computers. Do you know any other programs that I can use and that is easy to learn?
