Pat and all, Thanks for a great piece of software! I am learning the software through the examples and provided datafiles (="newbie"). We have a student here with a huge dataset so we are testing a few different platforms and hardware setups.

When running the command: mothur > filter.seqs(fasta=sogin.unique.align, vertical=T) The command will work using the provided datasets. When using my own dataset, carefully prepared and double-checked, I consistently get a "segmentation error" followed by Mothur crashing/exiting to the terminal window of my server.

Any idea what this means?

We will be releasing a new version on Monday, which may fix this. Could you email me a copy of the sequences that are having the problems? Also, please sign your entry with "--~~~~" in the future. --Pat Schloss 20:38, 7 August 2009 (EDT)
