Reading s2p file with power sweep at a certain frequency

I wonder if there is anyway to import s2p file to Matlab (similar to the command "sparameters('filename.s2p')")

But this time I'm measuring the S-parameters while I'm sweeping the power at a certain frequency (unlike the usual s-parameters where you sweep the frequency at a certain power)

When I try to run this command

sparameters('860.s2p')

I get this error

Error using rf.file.touchstone.Data/read
In the Touchstone format, frequency data must be non-negative and
increasing.

Error in rf.file.touchstone.Data

Error in rf.internal.netparams.AllParameters/readRFFile

Error in rf.internal.netparams.AllParameters

Error in rf.internal.netparams.ScatteringParameters

Error in sparameters (line 80)
            obj =
            [e-mail](varargin{:});

The s2p file is attached and here is a sample of the first lines of the s2p file

!S2P File: Measurements: S11, S21, S12, S22:Power Sweep
# Hz S  dB   R 50
-25 -7.2184515 -54.525898 -200 45 -200 45 -200 45
-24.99625 -7.2030401 -54.556015 -200 45 -200 45 -200 45
-24.9925 -7.210341 -54.558491 -200 45 -200 45 -200 45

Your help is appreciated!

Thanks in advance!
