r(601) /var/folders.... error

[Anuska Corbin]

Hi I am trying to perform matching using the nnmatch command but I get an error.

This is my code:

nnmatch re78 treat re74 re75 if sample1==1, robust(1) pop m(1) replace tc(att)

This is the error: file /var/folders/qw/6ryht6lj3p7998s_nz5t_zvc0000gn/T//S_29673.000003 not found

Does anyone know how to fix this?

I am not familiar with nnmatch, but /ver/folders/ is where Stata for OSX puts temporary files. Are you able to write to that directory? Rebooting is supposed to clear it of old files. There are instruction for using a different directory at
