To expand on Jami's answer, although it's very enterprising to convert a BED file to BAM, the files have very different focuses on the types of data they support and the experience of viewing the converted data would be approximate at best.
Similarly, FASTA or GFF would not convert well to BAM. As Jami mentioned though, we plan on building built in support for converting all of these file types in the future.
For the moment, we are "bootstrapping" GenomeBrowse with the technology of SVS. This means for viewing annotation sources GenomeBrowse relies on annotations being converted to our efficient binary IDF file format.
SVS produces IDF files when converting BED, FASTA, GTF or any text file downloaded from the UCSC genome browser table viewer. GenomeBrowse is set up to auto-detect files that SVS converts, and they are ready to plot the next time you go to the Add dialog.
SVS is Golden Helix’s analysis product for a variety of workflows and is a commercial tool, you can request an evaluation of SVS through the evaluation request form.
