I have a collapsed fasta files with all my counts and the corresponding sequences. I would like to annotate those sequences onto a gff file to find out what they are. Is this possible? Usually I would need a bam/sam file, but I dont have that for these sequences.

So map the collapsed fasta file to something and then count accordingly. Just make the counts part of the read name so you can get them back later. BTW, you made your life more difficult by collapsing things like that. Aligners are fast enough these days to handle whatever size data you want to throw at them.

Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.
The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
