It might be useful to note that the chromosome name scheme should match what is in the index file associated with the tabix file. Your documentation uses Ensembl's scheme ("1", "2", etc.), but some labs use the UCSC scheme ("chr1", "chr2", etc.). If a different chromosome name scheme is used, no data gets returned, which can cause confusion.
