Title: Fix possible problems if qsignature doesn't run and more code style changes

more code to fix some code styling typos, and prepared qsignature to run with whole genome when we have an idea how to update resource.

it is working running in local and with ipython. Also working if there is no qsignature tool or vcd file. As well, add to create index if there is no.
