Error with Undefined Class 'GtoolsResults' in wooldid Command

[Trevor Fitzgerald]

Good evening,

I am hoping someone can help me with the below issue:

I am encountering an issue when running the wooldid command with the following syntax:

wooldid readmission cohort disp_month replace_month, cluster(mtf) controls(pat_race_white elixsum pat_sex_female pat_age) fe(hcpspec msdrg)

The error message I receive is:
class GtoolsResults undefined
(282 lines skipped)
(error occurred while loading _gtools_internal.ado)
r(3000);

Potentially important information:
1. I am operating in Stata 18.0 SE
2. I am operating on Amazon Appstream on a government program (I cannot install .ado files, they must be screened and imported)
3. I had my entire .ado folder imported from my personal computer into the cloud system (the command works perfectly on my home computer for a different project)
4. gtools version is 1.10.1 05Dec2022

I found one related post in 2021 but nothing that seemed to fit fixing this issue: https://www.statalist.org/forums/for...o-admin-access

Any help understanding what could be causing this issue would be very helpful.

Looks like it requires gtools, which is not installed.
