work-arounds for data entry on more than one computer
Epi-Data users:
What strategies have you used to get around the limitation of only being able to input the data on one computer? We are thinking of splitting the file into two - with Type A respondents in one file/on one computer and Type B respondents in another file/on a different computer and then combining the resulting datasets in Stata. Will this work? Are there other/better strategies?
Thanks, Kristine Hopkins khopkins@prc.utexas.edu
We have 5 different diagnostic summary sheets for subjects in a study I'm working on. Since they are not necessarily completely at one time, we decided to enter them in separate files to have all the data available as soon as possible. I put the 5 sets of entry files (.rec, .chk, and .eix) files on a shared drive where anyone working on the project can access them for entry. Everyone doing entry has Epidata on his/her own computer.
I also put a SAS program there that calls a Epi-c batch file that creates SAS files and then merges them into a SAS dataset with all the data from the various files so anyone in the group can easily create a merged file with all the data. It doesn't work if any of the Epidata files are open, but this has only been a minor problem so far.

Dear Kristine:
How about making use of EpiData Analysis to append files with the same structure:
close erase "allcombined.chk" erase "allcombined.rec"
copyfile "a.chk" "allcombined.chk"
read "a.rec" append "b.rec" append "c.rec" append "d.rec" append "e.rec" .... savedata "allcombined.rec" close read "allcombined.rec"
Regards,
Hans

Hi Kristine,
If you are entering data into split files and you make changes to the value list options frequently, I think it is also a good idea to store value lists in separate .rec files as then you can link all your split files to the same lists and only have to update once for each change. Of course this only works if you are on a network or all files are on the one computer.
