sorry if this has already been discussed - can’t find any threads on this topic.
Hi Pat and Sarah,
I am using pre.cluster() in a batch file following unique.seqs. This is for de-noising MiSeq sequences. It seems that pre.cluster does not find the name file as I get the following warning: “This command can take a namefile and you did not provide one. The current namefile is MSB\_index25\_9864.chop.good.filter.names which seems to match MSB\_index25\_9864.chop.good.filter.unique.fasta.”
The .map file output by pre.cluster indicates that the name file was ignored.
thanks,
Giovanni Widmer

are you using name=current when you run pre.cluster?

I did not. I wasn’t aware there was such a thing…thanks for quick reply, much appreciated! Congrats on the 1000 citations : )
