Hi, does anyone know of a parser, preferably in R, for the Tiled Data File (TDF) format that is used by the Broad's IGV Browser?
The TDF format is binary, but appears to be poorly documented. It looks like it is mostly intended as an intermediate file format to speed up IGV, and the Broad's igvtools can generate TDF files from other sources. Unfortunately, there is no method for converting/dumping TDFs into, say, plain text.
The background is a need for reading TDF files published on GEO, e.g. http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE70991
