I am trying to import mm10 ChIP BED file datasets from GEO for use with: 

enrichPeakOverlap

downloadGEObedFiles(genome="mm10", destDir = getwd())

However I am getting the following errors, not sure what the issue is:

trying URL 'ftp://ftp.ncbi.nlm.nih.gov/geo/samples/GSM1308nnn/GSM1308182/suppl/GSM1308182_HaloSox2D.bed.gz'

Error in download.file(fnames[i], destfile = destfiles[i], mode = "wb") :

In addition: Warning message:
In download.file(fnames[i], destfile = destfiles[i], mode = "wb") :
  cannot open URL 'ftp://ftp.ncbi.nlm.nih.gov/geo/samples/GSM1386nnn/GSM1386022/suppl/GSM1386022_4cell_mc_CG_raw.bedGraph.gz': FTP status was '550 Requested action not taken; file unavailable'

By visiting GEO, https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM1386022, I find that the `raw.bedGraph.gz` file was removed and instead they provide `bed.gz` files.

1. I need to update GEO meta information.

2. Need to change `downloadGEObedFiles` to tackle with this situation, since I can guarantee the GEO meta info is always correct even it was updated frequently.
