st: Use of polychoricpca with imputed data

I have imputed my dataset using the 'mi ice' command in Stata 11 and I would like to run a principal component analysis, using the 'polychoricpca' command, on the imputed data. I am interested in saving the extracted component to the dataset to use it in my analyses.
I used mim2: polychoricpca varlist, pw score(outcome) nscore(3)
But I received the following message:
command polychoricpca not recognised by mim; try specifying category option
r(198);
How can I specify the category option?
Cheers,
Francesca
