errror: Error in reading your fastafile, at position -1.

Hello,

I’m totally new on mothur and on bioinformatics too. I am following the tutorial of this wiki. The first command that i tried (align.seqs) i found this error:
Error in reading your fastafile, at position -1. Blank name.
So I though the problem was with my fasta file and I tried with the files of the Esophageal community analysis examples. I did the command:

mothur > align.seqs(fasta=esophagus.fasta, reference=core_set_aligned.imputed.fasta)

Reading in the core_set_aligned.imputed.fasta template sequences…

Error in reading your fastafile, at position -1. Blank name.
Error in reading your fastafile, at position -1. Blank name.
Error in reading your fastafile, at position -1. Blank name.

And I needed to abort the terminal.

Does anyone could help me?
Thank you very much for help!

Could you tell me what version of mothur? What OS are you running?

3

I’m using mothur v.1.25.0 and my OS is Linux!
Thanks for answer!

4

Could you send the complete logfile to mothur.bugs@gmail.com?

5

forgive me but what is the “complete logfile”??

Everytime mothur runs it creates a logfile. It should have a name like mothur.1335814360.logfile.

Thanks for sending your logfile. I noticed you are running mothur version 1.18.1. We had a similar bug report with people using g++ 4.6. It was corrected in version 1.22.1. Can you try downloading our current version, 1.25.0, and see if you still have the problem?
