first of all, a disclaimer: I know very little R .

So, now. I installed chimera on our R 3.1 and all worked fine.

Then we updated R and bioconductor to R 3.2 and bioconductor's version 3.1.  I followed the same steps to install chimera, and it is supposedly properly installed. The library loads with no errors, but now it crashes on my first script line:

> fusionevents <-importFusionData("star","../RVM_CChimeric.out.junction",org="hs",

The following chrs were removed from fusion acceptor:
 chrGL000191.1 chrGL000192.1 [...]

The following chrs were removed from fusion donor:
 chrGL000191.1 chrGL000192.1 [...]

Importing 8 fusions

Error in (function (classes, fdef, mtable)  :
  unable to find an inherited method for function ‘findOverlaps’ for signature ‘"GRanges", "NULL"’

Thanks for any help!

HI Kelly,

could please share with me your data set to reproduce the error?



P..s can you please  put it in a shared dropbox or send by email to

I figured out what the error was. In the previus version it would accept org="hs" , in this one it has to be org="hg19".


thanks, and sorry for taking up your time.

thanks for working this out, Kelly


Raffaele: are you able to fix the working example ( now, or do you have to wait until the next release of chimera?

all the best,
