Dear Sir/Madam;

I have a difficulty in using gwarpreg.ado at http://www.stata.com/stb/stb30/snp10/ by Nonparametric regression.

It requires another input file named "resfile" which I don't know how to create. (as following the picture)

The programming (procedure ResulFile) should automatically create the "resfile". I don't know why it can't create?

Could anyone tell me what's wrong? Thank you very much.

Best regards,

Chao-min Tsai
