Bug in Epidata Entry?
by epidata-list＠lists.umanitoba.ca 29 Oct '09

29 Oct '09

Hi, I programmed a lot of diffent entryforms in Epidata but now I sometimes get a errormessage "window has no scrollbars", when I try to open a rec-file in epidata entry by doubleclicking it in windows-explorer (Win XP, SP3). This only happened with files, that use a big data-file for a "comment legal" command in the chk-file (icd-code table with 14000 entries). It seems to work, when I start epidata as a window (not maximized!) and then open the rec-file. Or if I closed epidata entry before as a window (not maximized) and then double click the rec-file in win-explorer. If I close epidata maximized, the parameters in the epidata.ini-file are: ... MainWinTop=-4 MainWinLeft=-4 MainWinBot=998 MainWinRight=1284 MainWinMax=1 ... (My monitor resolution is 1280x1024). Is this a bug in Epidata entry? Does anybody had similar problems? Greetings Juergen

Does the "999 limit of text" apply to both the QES and CHK files?
by epidata-list＠lists.umanitoba.ca 29 Oct '09

29 Oct '09

In the data entry module ts is advised that "All fields must fit within 999 lines of text" Does this apply to the qes as well as chk files? regards martin -- Martin Alhassan Adjuik Statistician (INESS) INDEPTH Network Secretariat Office : +233 (0) 21 521670 Cell : +233 (0) 243714441 martin.adjuik(a)indepth-network.org madjuik(a)gmail.com

Lost all my code as a result of a system error
by epidata-list＠lists.umanitoba.ca 28 Oct '09

28 Oct '09

Yesterday I was working on a questionnaire (over 300 variables) and at an advanced stage, got this message "Access violation at address 0048AC7 in module Epidata.exe. Read of address 00000000". I lost the whole work after it will not allow me to save. I started anew but this time I backed up the chk file at different stages of the developmeent of code (has a lot of skip patterns and replace of values in all places which have been skipped). The problem has appeared occurred agian and naturally have lost the code I was building from this afternoon. Has this happened to anyone before and if so how did you resolve it?

Selection of cases with special digits within a longer variable
by epidata-list＠lists.umanitoba.ca 27 Oct '09

27 Oct '09

In Denmark, we have the unique CPR number consisting of birthdate (ddmmyy) followed by 4 numbers. If I have to select a population born in fx 1940 from a larger epidata-fil, I consider to use the export facility, but then need an observation filter only selecting those born in 1940, which means those numbered 40, in position 5 and 6 in the 10 digit CPR variable. Do anybody have knowledge of a relevant syntax for that? Yours sincerely Jes Lindholt Ass. professor, PhD Vascular Research Unit Viborg Hospital, Denmark E-mail: jes.s.lindholt(a)viborg.rm.dk

Re: Rename fields
by epidata-list＠lists.umanitoba.ca 22 Oct '09

22 Oct '09

Ziad, First of all always backup your data before doing dangerous things such as renaming variables. That is simple. The first sugestion is to use EpiData entry tools menu... there is something like rename fields(my menus are in portuguese) ... this may help. Another solution is to export two splits of the dataset to stata, one containing the first the datebase but without the second datebase and a second dataset with only the unique identifier and the second datebase. Later, already with stata, you may rename the varibles and merge the two datasets side by side with the unique identifier. Best regards, Abraço forte e que a força esteja com você, Dr. Pedro Emmanuel A.

Hi! I have had 2 date related vaiables called "datebase1" and "datebase2" in EpiData. When exported them into STATA, they are showing as "datebase" and "datebase" and both variables contain the same value now which is not correct. It might be due to the total number of characters for the variable name, but my question is how can I fix it? Best regards ziad

I guess, you have to go back to your REC file, go to Tools | Rename fields, and change each of the two fields to names with 8 or fewer characters. While it is nice that EpiData offers a maximum field length of 10, it might be wise (as example shows) not to exhaust the maximum if the data are to be analyzed in other software limiting the allowable length to 8.
