blast database can probably be build with docker

[antonkulaga]

You have:

# if you do not habe BLAST+ installed run:
$ sudo apt-get install ncbi-blast+
	
# go to the place where Uniref fasta file is being stored (change the path bellow accordingly):
$ cd /Place/where/UnirefX.fasta/file/is/stored
	
# create database (this might take a while from several minutes to one hour)
$ makeblastdb -dbtype prot -in uniref50.fasta

There is an official docker for ncbi-blast, maybe you can just do it with it. Can be either docker command or cwl-task

We could add this and also options for updating the databases (uniref updates every 3 months). Also, I still need to check whether the predictors behaviour is consistent with different versions of protein databases...
