Dear Mothur users,
I was wondering if it is possible to merge groups in a “.shared” file.
E.g. if I would like to generate a Venn diagram on basis of a “.shared” file that contains 6 groups I would get “Error: Too many groups chosen. You may use up to 4 groups with the venn command”… which makes perfectly sense of course.
However, if my shared file contains e.g. 3 groups of Winter sequences and 3 groups of Summer sequences, would it be possible to merge those groups in two “seasonal groups”? This would allow me to generate a Venn diagram (or tree, pca etc.) based on those seasonal groups.
Obviously I could merge fastas and start from scratch but I am always interested in short cuts.
