We have problem with this command Trim.seqs (fasta=M01.fasta, qfile=M01.qual, qaverage=40, oligos= BARCODE.oligos)
Error : In sequence xxxxxxxx xxx xxxx quality score s, expected a number and got >xxx xxxxx xxxx, setting score =0
This type of error typically happens because the files were processed before you start using them in mothur. Is that possible? Can you ask your sequence provider for the raw, unprocessed, data?
It was made by illumina seqs and I don’t have R1 or R2 data, I extracted from the mapping the fasta and fastq and fasta qual.
I’d strongly encourage you to try to track down the raw data. I’m not sure how publishable the data will be if you can’t post the raw data to SRA.
Mmm… that is should it work with data fastq?
How would that be possible in mothur?
I’m not sure what you’re asking, but mothur has a
fastq.info command to separate the sequence and quality score data and
make.contigs uses fastq files as input. The preferred approach is
make.contigs with the original fastq files.
Hi my raw seqs is single end
Then you would use
trim.seqs. But you would still need the original fastq file
