My solution won't work for Nirali if she wants to run sections of a do-file instead of the entire file. The temporary do-file that the Apple Script creates won't know about the local macros. There are two solution:


1. Use global macros

*************************************************
global dat1 "~/Documents/Curr_Proj/project/data_1/" //path to data_1 with "/" added to avoid typing
global dat2 "~/Documents/Curr_Proj/project/data_2/" //not used here, but handy if you need it

use ${dat1}d1_01, clear // Note the curly brackets
(some commands)
save ${dat1}d1_02, replace
************************************************

2. Start the do-file and then change the working directory to the data directory. This might be the easiest solution.

*************************************************
capture log close
log using p01, replace text // Start the log in the do-file directory

cd "~/Documents/Curr_Proj/project/data_1" // -cd- means "change directory". Note there's no slash on the end.
use d1_01,clear
etc.

Nirali, I think now that I understand your problem. Your data is not in the same directory as your do-files. Now that you are starting Stata from your do-files with the dataninja script, Stata doesn't know where the data are. The solution is easy: in the do- files (not the script) tell Stata where to find the data.

Here is the method I use. I create local macros to make it easy to refer to the data sets. Suppose your data are in two different folders, data_1 and data_2 inside a "project" folder. Create the following macros:

*************************************************
local dat1 "~/Documents/Curr_Proj/project/data_1/" //path to data_1
local dat2 "~/Documents/Curr_Proj/project/data_2/" //not used here, but handy if you need it

use `dat1'd1_01, clear // use a data file in data_1
(some commands)
save `dat1'd1_02, replace // save the changes in another file (never the same one!)
************************************************

Another possibility is to change the directory to your


To find the path to the do-files in BBEdit, I click the blue "i" button at the top of the document; one of the options is to copy the path to the clipboard. I'm sure that you can do the same in Text Wrangler. Tip: keep both the do-file and log folder and the data folders open where you can see them.

Good luck!

Hi,

I recently downloaded the stata scripts from Dataninja. One of these scripts allows you to send your do file straight to stata. However, it appears that it also automatically changes the path directory to the path directory of the do file. Since I keep my do files and data files in different folders, every time I try and run a do file from Text Wrangler, Stata tells me that the data files are not found.

Aside from inserting a change directory line into each of my do files, is there a way I can change the script? I don't know anything about scripting language - what would I have to look for or write?

Thank you,
Nirali
