Bug in isBedQuerynameSorted()

[kridsadakorn]

Hi,

I tried to use snap_pre to create snap object from BED files.

However, it always reports as error: ./test.bed is not a sorted by read name!, even I have sorted them.

I see that, in the code of the function isBedQuerynameSorted(), at line 166

cur_barcode = str(item).split()[3];

, perhaps this line is wrong, and it causes the error.

Should the string be split the same way as in the function getBarcodesFromBed(input_bed), line 256?

barcode = _read.split()[3].split(":")[0].upper();

Please check. Thank you very much.
