make.contigs sometimes fails to make group file

Dear mothur maintainers,

The make.contigs command such as

make.contigs(file=foo.files, processors=n)

seems to fail to produce the group file when the number of pairs of fastq.gz files in the file file is lower than the number of processors, as given by the processor parameter. All is fine when I’m using decompressed fastq files or when I’m using fewer processors than there are pairs to process. This happens with mothur version 1.37.4, binary Linux version downloaded from GitHub and tested on RHEL 6 and Debian 8.

Let me know if you need any other information,

Thanks for bringing this to our attention. The fix will be part of our next release.
