The reading should stop after the first 3 rows of data. That is easy to fix. I will look into handling multiple distance matrices in one file ... there seems to be some incomplete code in neighbour but at least EMBOSS should gracefully load them. That will take a little more effort because it involves some changes to our port of neighbour, but is not difficult (he says confidently!) We also need to update the phylip code in EMBOSS to the latest release. It would help to know how many users are working with the EMBOSS phylip. regards, Peter Rice _______________________________________________ EMBOSS mailing list [email protected] http://lists.open-bio.org/mailman/listinfo/emboss
