Perhaps you first might explain which file (format?) you're talking about (and how you obtained it?)

program code which can be used to open the fastaq ftp file

There is either a fasta format file or a fastq format file. There is no such thing as a fastaq file. Either format should be plain text (compressed if it has .gz extension on it). Files can be checked using less/more/cat for plain versions or zless/zmore/zcat for compressed versions.

I think you first need to get a background on what these files are (both SRA based on your previous question) and now fastq (sequencing data). Spend some quality time reading some introductions (use google). If you are already stuck in opening/looking at these files, any downstream analysis will be...difficult. There are many good tutorials out there. Check out software such as BWA for alignment and samtools for manipulation of output files. They all have good documentation and associated papers/publications/manuals.
