Some questions about cgmaptools mfg and mtr

[TuoCai2000]

Hi, thank you for developing cgmaptools!
I would like to calculate the methylation level of specific genomic regions like cgi / genebody. Then I tried two ways to calculate it but i got different results.
First,I used cgmaptools-bed2fragreg to split the bed files into 1 region(-n 1),then I used the output file as the input of the cgmaptools-mfg command ,then I get the mfg files,the "total_ave_mC" is the methylation level of the specific genomic region.
The second way to calculate is the cgmaptools-mtr, I just need to prepare the genomic bed files and then I need to calculate the mean value of the column"read(C)/#read(T+C)" of the output file.
However,I get different results.I wonder what's the difference between mfg(freg -n 1) and mtr? which is the correct way to calculate?
Thank you so much!

To calculate mC level for one region, the second way is suggested "ccgmaptools mtr".

The first way "cgaptools bed2fragreg" is to draw figure like Figure 7.4 in https://cgmaptools.github.io/cgmaptools_documentation/graphics.html#fragreg , which need to be feeded with a group of regions.
