Hi everyone,

I am having a coding problem while using SeqVarData function. I believe I've been using the same exact code with the same type of data and it worked perfectly so I don't know what I' doing wrong this time.

Here is the code I'm running:

seqData <- SeqVarData(gds, sampleData=annot)

And here is the error message:

Error in (function (cond) : error in evaluating the argument 'data' in selecting a method for function 'AnnotatedDataFrame': is.character(gdsfile) | inherits(gdsfile, "SeqVarGDSClass") is not TRUE

When I run

is.character(gdsfile) 

[1] TRUE

or

inherits(gdsfile, "SeqVarGDSClass")

[1] FALSE

If someone had an idea of what the problem may be, that would be super helpful! Thanks a lot!

I think you might have mixed up your objects, because the error message makes no sense to me. An AnnotatedDataFrame method should not be operating on a GDS object. Try restarting your R session and starting over, and if you still get an error, provide all your code (not just the last line) and the output of sessionInfo().
