# file file

The File file is 2, 3 or 4 column file containing the fastq files. Tired of creating the file file? Let mothur help with the make.file command!

The 2 column format consists of the forward fastq file in the first column and their matching reverse fastq files in the second column. This type can be used with an oligos file create a group file for your dataset.

small.forward.fastq    small.reverse.fastq
test.forward2.fastq    test.reverse2.fastq


... The 3 column format is used for datasets where the sequences have already had the barcodes and primers removed and been split into separate files. The first column is the group, the second is the forward fastq and the third column contains the reverse fastq.

... The 4 column format is for use with index files. The format is forward fastq file then reverse fastq then forward index and reverse index file. If you only have one index file add ‘none’ for the other one. Here’s an example with just a reverse index file:

My.forward.fastq My.reverse.fastq none My.index.fastq


mothur will process each pair and create a combined fasta and report file with all the sequences.
