Dear Galaxy Community
I frequently use pileup files in galaxy.
The sequence read column contains characters like .,AaCcTtGgNn$* etc.
I would like to be able to add a column to my tables that represents the number 
of instances of a given character in the read column.

I can do this in excel with this type of formula:
=len(I2)-len(substitute(I2,"A","")

But of course, Excel can only handle a limited number of total lines.

Do we have this functionality in Galaxy?
If so how?
If not..... please?

Thank you,
