STRUM figure manipulation

Hello to everyone,

this might be a very naive question but is there a way of changing some graphic parameters for producing a good quality output figure from STRUM? We have done a STRUM analysis but the output figure resolution is quite low. Is there a way of changing that? Alternatively, given the output mutability file, is there a package in R where this file could be used as input in order to get the desired figure in high resolution?

Thanks for any help!!!
