custom protein database #56
Comments
Hi @shlomobl I am afraid that in the current version of tormes, only custom nucleotide databases for gene search are possible as an integrated option. We have included the chance of custom amino acid database searches in the ongoing development version of the tool, that we hope to release after summer. I will keep you posted.

Hi, |
Hi @shlomobl Sorry for the late reply. Both doing a BLAST or adding the proteins to the annotation files for the analyses are straightforward processes. However, from the latter you might retrieve back the information from the genes you are looking for. If you would like the results to appear in the tormes report, it would require some expertise with r-markdown language, which is the one used for the generation of that report. If you don't have experience with this, I would encourage you to wait a bit until we release the next version, which will allow the usage of protein databases for direct "blasting". In the meantime, if you would like to look for some proteins in your dataset with BLAST, you need to make a blast-formatted database first:
Then, you can run BLASTP over the predicted protein file performed by prodigal (and/or annotated with prokka). For instance:
As I said, I hope we can release the next version soon. Best, |
Hi,
Yes, please, I appreciate it!
Especially if results can be summarized in a presence/absence table with
all genomes, similar to VFs/AMR.
I guess it is easier to generate a table from BLAST than by adding these
genes to annotation?
Thanks!

In the meantime, if you want to use an amino acid database I can guide you
to do so by using blastp and by taking advantage of tormes hierarchy of
files. Would that be an option for you?
The predicted proteins of your genomes would be in the gene_prediction or
annotation directories (depending the option you used for run the
pipeline)
Additionally, you can add those proteins to the database that is used for
annotation with prokka and to look for them in the annotation results.

Hi,
I am analyzing multiple bacterial genomes with very little programing knowledge. The way tormes parses and summarizes the results from all the genomes in tabular files is very helpful!
Tormes has now an option to query the genomes with a custom nucleotide database. But what I have is a protein database... is there anyway to do this with tormes? Any other suggestion? In the end, I'd really need a genome X protein sort of table...
Thanks!
