My scripting skills are the problem... I know some basic shell stuff like grep, sed, awk etc. I come more from the wetlab. Using pre-existing tools and some mild reformatting is ok for me. But I am not sure how to approach this...
I am still trying to learn some biopython in my spare time...

You can convert to fastQ using a perl script helpfully provided in these forums - I've done this in the past, you'll have to search for it. Then as you say manipulation is easier.

I don't think you'll find any tool. Sounds like is time to put your scripting skills to work ?

Splitting fasta AND quality on masked sequence
Hello,
does anybody have a script or any program that allows me to split fasta sequences and the according quality file on masked bases such as "N"? Everything I find works perfectly on fasta files but the quality files are never touched. I think even FastQ format would be ok because conversion is easy these days using Galaxy.
Any help would be appreciated.
Cheers,
Markus
Example:
>fasta
GACTAGCGATCGACGATCGNNNNNNGACGAGCGACGAGCGA
>qual

Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...-

Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...-
