RnBeads save.rnb.set error in ffsave

Question

[Ewout]

Hi,

I'm am a PhD student coming from a non-bio-informatics background dipping my toes in RRBS analysis using RnBeads.

I imported Bismarkcov files using the rnb.run.import function. I next wanted to save the RnBiseqSet object with the save.rnb.set function. I get the following error for (all) my files:

Error in ffsave(list = ls(ee), envir = ee, file = ffFn, ...) : the previous files do not match the rootpath (case sensitive)

All mentioned files are of the format .ff and are located in the directory ~/Rtmp2BkJtI/ff

When I look at the save.rnb.set code, I see that it uses getOption('fftempdir') as argument for rootpath:

rootpath=getOption('fftempdir')

When I simply run getOption('fftempdir'), I get exactly the same directory as the one my files are in:

~/Rtmp2BkJtI/ff

Any suggestions how to remedy this issue?

Kind regards,

Ewout

For those interested, my error was caused by the fact that ffsave cannot handle ASCII symbols like "(" in file locations.
