Hi, I have successfully installed CAGEr version 1.22.3, and successfully tested the example codes in the CAGEr guides (http://www.bioconductor.org/packages/release/bioc/vignettes/CAGEr/inst/doc/CAGEexp.html). In the CAGEr example, the input is CTSS files. Now, I tested using "bam" format as input files. After constructing the CAGEexp class, I can run run getCTSS with  parameters "correctSystematicG=FALSE,removeFirstG=FALSE". When I set "removeFirstG=TRUE",  the error message said "Error in checkSlotAssignment(object, name, value)". Could this be a bug or my mistake? Thank you!

> i.ce <- CAGEexp(
+     genomeName = "BSgenome.Bterrestris.bcm.bter1",
+     inputFiles = "/path/to/bam/file/file.bam",
+     inputFilesType = "bam",
+     sampleLabels = "test"
+     ) 
> getCTSS(i.ce)
