I would like to have sequence with corresponding quality values according to length distribution of sequences of fastq in as such fastq output. suppose i want to extract that reads which falls sequence length of 16, 17, and 18. please keep in mind that my fastq reads in color space.. exp:

@5521_14_238_F3

any tricks by one line bash commands or by perl (without using bioperl modules)???
