Dear fellow scientists!
I'm new in the field and need some help with a small problem.
I have an .aln and .fas files of aligned nucleotide samples.
For phylogenetical analysis, I'm using BEAST program which requires the input file to be in NEXUS format (especially .nex not .nxs).
I've tried many options but just keep getting errors.
Do you know how can I properly convert FASTA or alignment file to NEXUS file?
