Raw sequence only from online sources?

[Joh Johannsen]

Looking for raw data only for entire chromosomes for a set of related species, something like files only containing millions of "acgt" and nothing else. Any suggestions for how to create these?

Right now I'm using ".fa" files from different sources (ncbi, ensembl, uscs), and processing those to strip out the things I don't want. Is there a better way?

Well, why not use fasta files ?

Furthermore I am unsure to fully comprehend your interrogations.

Here the things you don't want are the header I presume.

If these files are for programming purposes, you can always keep this files as they are and simply skip the headers.
