bedgraphToBigWig error

Hello,

I would like to transform a BedGraph file into a BigWig file using R. For this purpose I run the next code:

Bedgraph <- import_bedGraph('//nasibv05/datos/Grupos/UGC/RROxBS/KO1_BS/KO1_BS.bedGraph')

bedgraphToBigWig(Bedgraph, genomeSizeFile = "//nasibv05/datos/Grupos/UGC/RROxBS/KO1_BS/KO1_BS.bedGraph", ucscPath = "/opt/UCSCtools/",
                 outDest = "//nasibv05/datos/Grupos/UGC/RROxBS/KO1_BS/", outSuffix = "KO1_BS.bigwig")

And I get this error:

Error in dir_check(ucscPath) : Directory /opt/UCSCtools/ does not exist.

I would like to know what I need to write into the ucscPath argument in order to make the function work properly.

Thank you!

Make sure you have UCSCtools available in the mentioned location. If you are using E-myers/rnaseq , the bedgraphToBigWig function is a wrapper of the bedGraphToBigWig binary. Also, the genomeSizeFile parameter expects a text file containing the genome size information.
