Error when using sigdigit in individual NCA

NCA
1

Hello,

I am running a simple NCA analysis but i get an error when i run the code for the individual NCA parameters. When i remove the sigdigit argument it runs.

Can you help me set the desired significant digits for the individual NCA parameters?

vz        = NCA.vz(pop_oral_ss, sigdigit=3)

i get this error :

ERROR: MethodError: no method matching vz(::NCASubject{Nothing, Float64, Nothing, Float64, Nothing, NCADose{Float64, Int64}, Float64}; sigdigit=3)

@achamzas, you are getting an error unsupported keyword argument “sigdigit”.
Try with sigdigits (plural) as specified in the run_nca function (NCA Docstrings · Pumas).

All functions in NCA.*.jl uses sigdigits, if I am not mistaken.

Sorry, originally I had tried with sigdigits and was trying different methods to see if it would work. I just tried again with sigdigits and i get the same error.

run_nca runs correctly using the sigdigits but i see there is a problem when i am trying to use the individual NCA parameters function.

Since you have a DataFrame back from NCA.vz function just do a data wrangling step:

@rtransform! df :var = round(:var; digits=3)

where :var is the column name of the NCA computation.

Thank you very much for your help.
