Hi Peter,
Hello all,
I'm currently trying to define a pair of integer parameters for min/max values:
<param name="min_size" type="integer" optional="true" min="0" value="" label="Minimum" help="Optional, but if used you must also supply a maximum value." /> <param name="max_size" type="integer" optional="true" min="0" value="" label="Maximum" help="Optional, but if used you must also supply a minimum value." />
As far as I can tell from the documentation, there is no way to write a validator which links the two parameters, for example in order to insist that min_size <= max_size?
I think you are right, there is no such easy mechanism. I would vote for a more powerful validator set.
In the meantime you can use a code file to check your variables. Please have a look at our wip DeSeq2 warpper:

or the excellent blog post from Ross:

Hope that helps, Bjoern
Yes, a helper Python script linked via the <code> tag containing a validate_input function may work here - thanks Bjoern :) However, according to the wiki the <code> tag is deprecated :( Peter
