I am trying to convert bedGraph files to bigwig. I cannot use UCSC's bedGraphToBigWig script because later I need to convert to wig files using UCSC's bigWigToWig script, which just converts it back to bedGraph.
I have found an alternative script to do bedGraph to wig, but I need the step size, and don't know what it should be.
What default step size does UCSC's bedGraphToWig script use? (Is it 1?) How do I know which step size I should use? What step size do the wig files output from MACS have? (Is it 10?)
(I can't use 1 because I run out of memory when subsequently running wigToBigWig.)
