Hi, is there anyone very familiar with RIPSeeker? I have tested it on my RIPseq data, I found some problems which I can't solve. My code as below:

library("RIPSeeker")
library("biomaRt")
library("curl")
library("org.Dm.eg.db")

outDir <- file.path(getwd(), "TEST")
# Parameters setting
binSize <- NULL     
minBinSize <- 11000 
maxBinSize <- 12000
multicore <- TRUE
strandType <- "-"   

biomart <- "ensembl"
biomaRt_dataset <- "dmelanogaster_gene_ensembl"
goAnno <- "org.Dm.eg.db"                    

seekOut.PRC2 <- ripSeek(bamPath = "/home/.../RIPSEQ/test", cNAME = 
                        "Non-...sorted.bam",
                        reverseComplement = TRUE, paired = TRUE,
                        strandType = strandType,
                        uniqueHit = TRUE, assignMultihits = TRUE,
                        rerunWithDisambiguatedMultihits = TRUE,
                        binSize=binSize, minBinSize = minBinSize,
                        maxBinSize = maxBinSize,
                        biomart = biomart,
                        biomaRt_dataset = biomaRt_dataset,
                        multicore=multicore, outDir=outDir)

I run the test data, the result is good, but for the ripRPKM, it reported errors with package “curl” .

When I run my RIPseq data, there are some errors. My library is a directional strand library from fly. I used Hisat2 (an subsitition for Tophat)for mapping, I tried both Dm3/BDGP6 as ref, I changed the strandType with “+”, “-”, “*”, and reverseComplement as TRUE or FALSE.

There are always some problems. When I set strandType = "-/+", reverseComplement as "TRUE/FALSE", the error is: Error in (function (...) : all elements in '...' must be GRanges objects Calls: ripSeek ... as -> asMethod -> do.call -> do.call -> <anonymous> I set the genomeBiuld as 'dm', 'dm3', "dm6", or just delete it, the final result seems no difference.

But when I delete the paired = TRUE and goAnno( If I keep goAnno, it will report less than 2 gene for GO enrichment), but my libraries are paired ends, it seems work. But when I check the RIPregions_annotated.txt, there are only a few information, these are all the results from RIPregions_annotated.txt:
