Here is a good start, but the easiest way to do that - i think- is learning by doing, try to watch online videos as tutorials on e.g. docking using autodock and schrodinger..etc, tutorials on how to perform virtual screening using avialable tools, how to do a qsar.

if you need to master tools don't look for courses just look for tutorials about that specific database or tool do, redo, ask if you faced errors and finally you would master that such as retrieving data and analyze it from drug databases.

otherwise most of avialable courses will not cover that diversity of tools you wish to learn and it would be loaded with much more you don't need for your research area, not to mention financial accessibility.

Dear Mohammad,

Thanks for your reply and links you provided. I have some expertises in molecular modeling using such softwares you cited but I would like to learn more about in silico target fishing for polypharmacological drugs (which integrates more statistics).

Best regards

these tools might help

- i think bioexcel had some professional workshops for that but i don't know if they have future plans for it

-EBI as well may provide future training on your  interest

-these articles as well focused on some statistical methods related to polypharmacological drug targets
