IndexError: list index out of range

[xiehui1991]

When I run "python -m jcvi.graphics.synteny blocks scz_zj2.bed blocks.layout", the last step of MCScan, it got a error that "IndexError: list index out of range". The details are as follows: [18:01:36] DEBUG Load file scz_zj2.bed base.py:34 Traceback (most recent call last): File "/home/houyan/.conda/envs/jcvi/lib/python3.6/runpy.py", line 193, in _run_module_as_main "main", mod_spec) File "/home/houyan/.conda/envs/jcvi/lib/python3.6/runpy.py", line 85, in _run_code exec(code, run_globals) File "/home/houyan/.conda/envs/jcvi/lib/python3.6/site-packages/jcvi/graphics/synteny.py", line 651, in main() File "/home/houyan/.conda/envs/jcvi/lib/python3.6/site-packages/jcvi/graphics/synteny.py", line 639, in main glyphcolor=opts.glyphcolor, File "/home/houyan/.conda/envs/jcvi/lib/python3.6/site-packages/jcvi/graphics/synteny.py", line 392, in init bed = Bed(bedfile) File "/home/houyan/.conda/envs/jcvi/lib/python3.6/site-packages/jcvi/formats/bed.py", line 147, in init b = BedLine(line) File "/home/houyan/.conda/envs/jcvi/lib/python3.6/site-packages/jcvi/formats/bed.py", line 50, in init self.start = int(args[1]) + 1 IndexError: list index out of range

Please help me. Thank you very much.

Can you make that the bed file contains tabs instead of space to separate the columns? It should be this format:

chr    start    end    name
