Someone asked off line how to accomplish this Situation: You have a file with say 1000 observations and you wish to encrypt the field containing social service numbers: 1. use epidata to make a qes file (tools menu - qes file from recfile) 2. edit the field in question from e.g. string field : v1 social id __________________________ to v1 social id <e > (same length) numerical: v1 social id ######################## to v1 social id <e > 3. Save the qes file 4. start enter data (point 4 on work process toolbar) and EpiData asks if you wish to update based on the revised qes file. 5. Do so and you are asked for passwords Thats all.

Setting up user rights in Windows XP can be very troublesome. It is not possible to give general advice for this, since there are very many local policies. In some places users have no rights at all, in other restricted access to one folder, ...... The EpiData programme as such does not read any of these rights and can be freely copied from one folder, memory stick or CD-rom or moved without "real installation", since the registry access is not part of the installation (unless you decide to associate file types with epidata). To work with rec and qes files the users need write access rights in that folder. So instruct the users to work on their default data folder - e.g. this could be "C:\documents and settings\mdi256\documents". But to share files btw. users you would need common rights to that folder. Also the file "epidata.ini" is saved after running epidata with current settings of screen, options etc. So the user needs write rigths for that or an error message box will appear at closing of EpiData. So in general: a. Let each user install epidata in their own data space (it is only around 2-4Mb for the whole programme) and each user can work independently. b Set up your pc such that each user have sufficient rights Jens Lauritsen Initiator and Coordinator of EpiData EpiData Association

Why Can I not use labels from EpiData in Epi Info for windows

This is part of the reason I started EpiData, because in analysis the labels are crucial as documentation. If you want to use the labels in analysis you will have to use EpiData Analysis which is getting closer to release. If your analysis is general crosstables, descriptive statistics and graphs the test version available at http://www.epidata.dk/testing.php will do the work for you. You could decide the strategy: 1. Do the basic analysis you have to do anyway with EpiData Analysis. 2. If you need to do further advanced analysis do the rest in Epi Info for windows (or other software) Regards Jens Lauritsen EpiData Association

You do not use the JUMP command, but rather use the logic you show in your message. Use the Edit button in the Check screen and type in the if statement. You have access to many useful functions as well - in this case the ABSolute value function. There are good examples in the help file accessible from within EpiData.

How to insert calculation in JUMP add/revise check
by epidata-list＠lists.umanitoba.ca 15 Mar '05

15 Mar '05

I am a new EpiData user. I am creating a data entry screen for anthropometric data. There are two weight measurements - and a third if the first two differ by +/- 0.5 kg. How can I incorporate this calculation in the JUMP section of the Add/Revise Checks so (1) if WT1 - WT2 GE 0.5 OR LE -0.5 go to WT3 (2) else go to HT1 [the next field] Thank you.

Re:Search problem

Could the problem be that the search is just marked as say 'forward' and you are sometimes already past the record you search for? Then marked 'search all records' instead or go to record 1 first.

"find records" not working properly
by epidata-list＠lists.umanitoba.ca 14 Mar '05

14 Mar '05

Hi all, I'm a new user of EpiData, and have a question regarding "finding records." When I try to find a certain case using a "Find Records" command, I sometimes get an error message saying "searching string(s) not found," even though the record I'm looking for is in the file. The identifier field I used is a numeric variable (caseid with four digits). Even more perplexing is for other data files, the "Find Records" works. I've created all data files in a same way, and don't understand why "Find Records" works sometimes, but not other times. Am I missing something or doing in a wrong way? I have a same problem with both EpiData 2.01 and 3.02 versions. Any helps or comments on this will be greatly appreciated. Best, Jin
