In mothur 1.33.1 using pcr.seqs on some reference files is producing errors like these:
[ERROR]: silva.bacteria.fasta6694.num.temp is blank. Please correct.
[ERROR]: 6675.temp is blank. Please correct.
[ERROR]: name mismatch in pcr.seqs
However, the file appears fine, and the hashes match a version produced without displayed errors in 1.32.1.
Easy to reproduce:
pcr.seqs(fasta=silva.bacteria.fasta, start=10000, end=20000, processors=8)
