Dear BioC users,

I have recently downloaded the dev version of affy and gcrma libraries (cf infra), as well as the dev metadata I need (cf infra) and when I launch a justGCRMA operation it gives me the error message below that I dont know how to interpret/use/correct.

Any help will be greatly appreciated.
