Hi, everybody,
I'm doing data analysis with my WGBS data with BSMAP.
I finished BSMAP(2.90)-alignment, methratio.py.
But when I run methdiff.py, I got the error as below;

.....When I run methdiff.py as below~

The result is..... (

It means, there is some error in "CHR1 374".
Also, further test shows there is some error in "CHR1 381".
with the error below~
Traceback (most recent call last):

File "methdiff.py", line 81, in conf_intv
span = z * (p * (1 - p) / d + z2 / (4 * d * d)) ** 0.5
ValueError: negative number cannot be raised to a fractional power
When I remove the chr1 374 in methratio result, there was no error.
so was when I remove the chr1 381.
Could you tell me some clue or comment for me?
Thank you very much, everyone.
