I used the STAR example and I am getting the follow error: Error in `dimnames<-.data.frame`(`*tmp*`, value = list(c("gene1", "chr.gene1",  :
  invalid 'dimnames' given for data frame

With the example "mcf7.FMFusionReport" from fusionmap it is working.

Hello Raffaele, 

I was wondering if there is a solution yet to the problem mentioned in this thread? I am facing the same problem and getting the following error on using the prettyprint function:

Error in `dimnames<-.data.frame`(`*tmp*`, value = list(c("gene1", "chr.gene1",  : 
  invalid 'dimnames' given for data frame

these were my command lines:

temp <- importFusionData("star", "filename.Chimeric.out.junction", org = "hg38", min.support = 10)

prettyPrint(temp, "temp.df.txt", fusion.reads = "spanning")

Any help on this will be highly appreciated. thanks!
