question on the rbias value

[yunjian-hash]

Dear developers,

When I calculated the rbias (rbias=bias-rct) value, I found this value was very different from the bias value. At the begining, the rbias value was similar to the bias value, however, the rbias tended to be very negtive and very different from the bias value (the largest divergence can be more than 100), which seems very strange. Is it correct? The attached is the input file and COLVAR file.

Looking forward for your kind reply,thanks input.txt COLVAR.txt !
