Show multiple mutations in the PCA plot

@gurdeep330 I'm testing this with 15 different sequences and it does run but PCA panel isn't visible. Can you see it or is it just me https://precogxb.bioinfolab.sns.it/output/XWLM8

Thanks for reporting this @maticmarin. This is arising because precogx internally assigns '_' to the sequence names before processing. I see that this led to some internal conflict and hence the error.

I have opened another issue to address this. Will update you ASAP. A quick way to avoid this, for now, is to replace _ in the sequence name with something else like, say ':'
You can quickly do this by typing: cat input.fasta | tr '_' ':' > newInput.fasta in your terminal. I did this for you already and here is the output.

Looking at the output, another question arose (@maticmarin @raimondifranc). Currently, if you input point mutations, it will display all the mutations (of the same protein) in the PCA plot eg: output. In other words, you must specify the "/" with the Uniprot ID or in the sequence name (if provided input in the FASTA format). I imagined that to be @raimondifranc idea. Or do you guys prefer to have all the inputs (even from different proteins) to be displayed in the PCA plot?

That also means @maticmarin, as of now, you will have to add '/' in the sequence names if you want to view them in one plot. It makes sense only if there are point mutations.
