Q: [Comparative RNA-Seq analysis] about seq2science HOT 2 OPEN

1. Does seq2science need to be fully rerun? No, seq2science can continue from the last possible point, as to save compute. There is a minor "problem", in that seq2science deletes some files to not save too much unnecessary stuff (called temp files). For your case, seq2science removes the trimmed fastqs after it is done with them, because otherwise it will keep both the raw fastqs as the trimmed ones. That's a waste of space! You can turn off the removal of temp files with --snakemakeOptions notemp=True. Make sure to check if this works as expected with --dryrun, because might just delete some files you wanted to keep after all...
2. Are the results stored in the same spot? Yes and no... The results of the quantifier are stored in the folder specific for the quantifier, so they won't overlap. The downstream results, for instance, the differential analysis, is stored in the same deseq folder. So those will be overwritten

So it is possible indeed. If you don't have too many samples then I think it is the easiest and least error prone to just run them in separate folders. However if you have a lot of samples, or are limited by compute/storage/time then you can reuse some of the seq2science output.

Adding to Maarten's asnwer: you can change the counts_dir and/or final_bam_dir in the config. That way, the final output is kept separately. Check out all configurable options.
