BS_Seeker 'original_BS' is not defined

[Gangcai]

Hi everybody,
I am using BS_Seeker(http://pellegrini.mcdb.ucla.edu/BS_S...BS_Seeker.html ) to process the bisulfite converted sequencing data.
There is no trouble for genome preprocessing steps(Preprocessing_genome.py), but there is error when running BS_Seeker.py:

part of the code:
python BS_Seeker.py -i $fastq_file -t N -e 50 -p $bowtie -m 3 -d $ref_genome -o $outfile

error:
....

ref seq: 0025 ( 27682 bp)

ref seq: 0092 ( 155270560 bp)

NameError: name 'original_BS' is not defined

I have re-checked the reference preprocessing, there is one error I missed:
"Could not allocate space for a joined string of 2897310462 elements.
Switching to a packed string representation."

I have fixed the preprocessing step, but "'original_BS' is not defined" error still exist...
