... How would I use Blast+ if my organisms don't have references or have the genes sequenced previously?? The reference species exists on ensembl so would that be an option? I do have a lot of reads, each species has over 1 million single-end reads. ...

... I use bwa-mem and samtools mpileup to align my species to a reference sequence for a few genes. My problem is that, first, the reference species is somewhat distantly related to the rest of the order I am studying. However, my real problem is that after running bwa-mem and gathering consensus sequen ...

... In PAML you typically run one alignment file and one treefile where the species names in the alignment have to exist and match exactly to the names in the treefile. So if I want to double my alignment by adding a gene, I'd have to attach something to the second set of species names like "sp1-2", "sp ...

... I want to test selection acting on one gene (set as my foreground) compared to a duplicate of the same gene (leaving it as background) but I'm not sure how to set up my files. I have alignments for the two genes, but this means I have to combine them into one alignment file. This means that all my s ...

... True! When I dug into it deeper and looked up their genomic regions they are indeed located at different points along the chromosome (but still close to each other). Even when reading deeper into a big paper that calls them isoforms, they actually described them as potential paralogs in a figure cap ...

... I'm reading up on fish osmoregulation and have come across many papers talking about the expression levels for a very important gene, atpase alpha (NKAa or atp1a1); it has many names. There are different "versions" that are well known such as atpa1a, atpa1b, and atpa1c where each one is expressed di ...

... BWA for one species generally isn't that long, it's that my script will automatically run it for 30+ species. The samtools sort however can take a freakin long time and I have no idea how to accommodate that. ...

... The alignment itself isn't long when I run it for one species - it's the samtools sort that takes a while too. But, my bash script will run the alignment for 30+ species which in total can take 2 days almost! I think I have to just add some pauses in the script which will somehow allow me to continu ...

... I'm trying to streamline my analyses using bwa and samtools on different servers but I am only allowed to run big processes for 24 hours before it stops processes. The way around this is to have scripts/programs pick up from where it left off (like rsync can do). Is there a way to make bwa and samto ...
