Weighted Unifrac

I’m trying to do a weighted unifrac using the command:

unifrac.weighted(tree=asli.fn.braycurtis.0.03.tre, count=asli.count_table)

but when I enter this command, mothur gives me the following error:

“[ERROR]: tag 66 is not in your count table. Please correct. Segmentation fault.”

When I open my count table, tag66 is present, so I’m no sure why I am getting this error.

The error massage include a space between tag and 66.

The error message does not include a space between tag and 66. Sorry about that.
