# randomFQ(1)

ea-utils: return random entries from the input fastq

## NAME

randomFQ - ea-utils: return random entries from the input fastq

## DESCRIPTION

Unknown option: h usage: ./randomFQ (**-c** \<count\> \| **-p** \<pct\>) \[-fasta\] \[-out \<prefix\>\] \[-seed \<int\>\] \<input-fastq\> \[\<input-2\> \[\<index-3\>\] \]

Returns \<count\> number of random entries from the input fastq.

Output is fastq, unless you specify **-fasta**

If the **-out** parameter ends in .gz, the result is gzipped in-place.

**-p** returns a % of total reads, **-c** returns a fixed count.

SINGLE END:

Outputs to standard output, unless **-out** \<file\> is specified.

PAIRED END:

Pass 2 (or 3) files as input, **-out** is required.

If the paired-end output contains a "%" sign, it is replaced with the 1 & 2 for paired-end.

IE: **-o** output\_%.fastq.gz

Otherwise it's jsut output\_1 and output\_2

\*\*\* If one file is an indexed read, it has to be the 3rd file (for now).
