[ensembl-dev] How to add custom motifs and transcription factor binding sites to VEP

I'm afraid your options are somewhat limited here. The custom caches, as
you suspected, are just for gene and transcript data.
You can use the --custom flag to look for overlaps with your features in a
gff or similar (
this won't do any sequence-based analysis.
I could see two possible routes:
1) Write a plugin to do the analysis. Without knowing the nature of your
data, it's hard for me to guess at what you might have to do in the plugin,
but I anticipate you'd probably read features from a tabix-indexed data
file and then proceed with the analysis from there. The dbNSFP and CADD
plugins do similar things (https://github.com/ensembl-variation/VEP_plugins)
2) Add your data to a custom Ensembl Funcgen database, and either use this
directly or build a cache from it. I have no sense of how hard or easy this
might be; our Funcgen team might be able to give some insight here.
