LAST output as SAM/BAM

[maubp]

LAST is not outputting MAF in the sense of MIRA Alignment Format (which is what my tool maf2sam.py converts into SAM/BAM).

You may have a look at this log file about how I converted maf to sam.

Im testing the sequence read mapping LAST (http://last.cbrc.jp/) But this program only outputs MAF alignment files. I tried using https://github.com/peterjc/maf2sam to convert to SAM/BAM but I get the following error:
command:

python maf2sam.py reference.fa al.maf

error:

[maf2sam] Identified 0 read groups
Traceback (most recent call last):
  File "maf2sam.py", line 514, in <module>
    assert line.startswith("CO\t"), line
AssertionError: # fraglen=217.0 sdev=146.778 disjoint=0.01 genome=6264404

Is there another maf to BAM/SAM converter? is there a way to output SAM/BAM from last
? Thanks
