How do I do with this error

[realzhang]

I ran DSS with some WGBS data, and after a overnight running with 50 threads on my culster, it showed:

Estimating dispersion for each CpG site, this will take a while ...

Error in split.default(1:n0, allchr2) : 组的长度为零但数据的长度大于零

May this be caused by spiked in DNAs? they are used with Chr name Lambda and pUC19.
And another question, DMLtest is extremely slow, which stays 0% for hours. I usually run it overnight, but if it errs like above I'll be very frustrated.
DSS is a great tool for DNA methylation analysis. Your work make life easier. Thanks.

I am also curious about the second progress bar. If the first row stand for dispersion estimation, what does the 2nd stand for?

I found that an extra space in the input file made this error.

For the slow speed of dmlTest, I am trying to use a less number of cores. (now using workers=10).
I guess allocate big BSobj among threads may cause huge time consuming.

The two bars are for the dispersion estimation for two groups. In a two-group comparison case, the dispersions are assumed to be different thus will be estimated separately.
