into the program CYANA. For each distance constraint there is a
line with the following data: residue number, residue name and atom
name of the first and second atom, respectively, the distance limit in Å,
and, optionally, the relative weight of the constraint. The default relative
weight is 1. Relative weights should be positive. The weight of a constraint
in the target function equals the relative weight times the weight ing factor for the corresponding type of constraints.

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
