'Circos.initialize_from_matrix' running error: x is invalid range of sector.

[qijt123]

When I run the 'Circos.initialize_from_matrix' function, I get an error. The error is as follows:

ValueError: x=0.6189621949302285 is invalid range of 'stroma' sector.
Sector = 'stroma'
Size = 0.6189621949302284 (0 - 0.6189621949302284)
Radian size = 0.64 (-4.63 - -3.98)
Degree size = 36.69 (-265.00 - -228.31)

Hi @qijt123

It appears that the error is occurring because the sector size should be 0.6189621949302285, but due to a rounding error in the floating point number it is 0.6189621949302284.

The maximum number of decimal digits that can be accurately stored in floating point numbers in python is 15, so if you truncate the number of decimal digits in the matrix to 15 or less beforehand, it should work correctly.
