The rho files are used to enter auto-relaxation (rho) and back-predicted diagonal intensities, I(0) values, into the program CYANA. For each spin there is a line with the following data: residue number, residue name and atom name, rho (in seconds [s]) and the I(0) value; the flag -1.0000 is used for keeping the fitted value.

all experimental values                                       class 1

The classes of experimental values:
H1N                                                           class 2
H2N                                                           class 3
single H on carbon                                            class 4
methylene not pseudo (chemically equivalent or overlapped)    class 5
methylene pseudo (chemically equivalent or overlapped)        class 6
methyl pseudo                                                 class 7

When there are rho values calculated from mean experimental values per spin-type:
