Hi All,

I have trying to preprocess my microarray data using RnBeads and keep getting error messages.

When trying to execute save.rnb.set(rnb.set, path=save.dir, archive=FALSE)

I keep receiving this error message: Inf WARNING Zip not found on this Windows system, this RnBSet object will not be saved. See the instructions for installing ZIP on Windows in the FAQ section of the RnBeads website.

I have been getting this error message whether I use archive=FALSE or archive=TRUE

I made sure to have Rtools and 7zip installed on the computer; however, it doesn't seem to be using these to perform the zip function and I am at a loss. I tried running the data without saving the rnb.set, but I think it may be affecting code later in the script. For example when trying to run: rnb.set.1=remove.sites(rnb.set, remove.illu$TargetID) I receive this error message: Error in open.ff(x, assert = TRUE) : file.access(filename, 0) == 0 is not TRUE. I am sure it is possible that these errors are not connected, but I am not sure.

Thank you in advance!
