I am having trouble calculating BMI in Epidata. Height is measured in feet (separate) and inches (separate). I tried to create a new variable (BMI), which it did, but it is labelled as "Float," and unusable. Please help! Ali Ali B.

Order of how yes no settings appear in tables
by epidata-list＠lists.umanitoba.ca 13 Oct '10

13 Oct '10

Hi Jamie A little while ago when you answered my question about changing the Boolean fields to 0-1, you mentioned there was a way in both EpiData Analysis and EpiInfo to reverse the order that two by two tables were shown, that would help in a situation where 0 was no and yes was 1 (so the 1 or yes answers appeared first in the table). I have looked around Epi Info but couldn't find a setting like this. Could you let me know how to do it? And also how to do it in Epidata analysis? I Many thanks Christine Christine Roseveare Analyst Regional Public Health 570 9194 027 495 9671 >>> Christine Roseveare 20/09/2010 5:21 p.m. >>> Hi Jamie Could you please explain why you changed the booleans to 0-1 before loading it into manager? Sorry if this is a silly question. I am asking because someone recently gave me an outbreak file where they had used 0 and 1 (created in Excel 0 = no and 1 = yes). The problem was that when I came to analyse it (in this case using Epi Info) it meant that the two by two tables were in the wrong order. Because no was 0 it came out first in the table. I have always used the boolean field in epidata for our outbreak questionnaires and it has worked very well. They come out in the right order in both Epidata Analysis and Epin Info, and also make intuitive sense to the data entry person. thank you Christine Christine Roseveare Analyst Regional Public Health 570 9194 027 495 9671 >>> <epidata-list(a)lists.umanitoba.ca> 13/09/2010 2:34 p.m. >>> I successfully loaded a moderately-sized .rec file (changing all booleans to 0-1 before loading into Manager--it should prompt to do that for us). Entry handled the existing and new data as expected. I would like to have the autojump to next field when all digits are filled. I assume that this is coming. I successfully loaded a fictitious file with just under 500,000 records and 12 fields (41.8 MB .epx from an 8 MB .rec). Given the capacity of removable memory today, size really isn't a problem. I cannot imagine ever having a real file that large. On my old Windows laptop, this file loaded/saved in 20-30 seconds, but GO TO any record in the file was instantaneous.

adding variables to existing rec
by epidata-list＠lists.umanitoba.ca 12 Oct '10

12 Oct '10

To add a variable to an existing REC file, I tried what was discussed on: http://lists.umanitoba.ca/mailman/htdig/epidata-list/2010q2/001427.html But I didn't have it very clear. I finally made it doing the following steps (using EpiData 3.1, under Microsoft Windows): 1) Editing the QES adding a variable with a temporally name as "new". 2) Then, Tools -> Revise Data File 3) Tools -> Rename Fields 4) I go to the new variable and then edited the subsecuent variables with a temporally name also. The added variable should finally have the name 'P1103e' and the subsecuent variables must be "moved". In that sense the new variable would be called 'newe' and the subsecuents of the same block of questions can be called 'newf', 'newg', 'newh', 'newi', 'newj', and so on. 5) Then, I just go again to Tools -> Rename Fields 6) I then rename the variables with the appropiate names as: 'P1103e', 'P1103f', 'P1103g', 'P1103h', 'P1103i', 'P1103j'. 7) Finally, I changed the QES file with the appropiate names and then Tools -> Revise Data File. This steps worked fine for me.

Alternatively you can ask each site to create an updated folder containing the updated rec.file then zip the folder before emailing it. Hope this will help too.

how to share epidata files?
by epidata-list＠lists.umanitoba.ca 08 Oct '10

08 Oct '10

Dear epidata-list members, I'm a new member and I'm quite new also in the use of Epidata. I need some support. My team is coordinating a multicentre study. At the beginning of the study we prepared a database (files .qes, .chk and .rec) and sent it to all centres; during the study they send back to us regularly the updated .rec files with the records. We have problems in receiving via e-mail, as attached documents, epidata files (especially files .rec with records, but also without records). We sometimes are not able to open the files, or sometimes we manage to open the files but the records are not there. We realised it depends also on the e-mail server used by every centre, and on other variables too. I wonder which would be the best way to share epidata databases. Many thanks Alessandro

New Sample file available
by epidata-list＠lists.umanitoba.ca 07 Oct '10

07 Oct '10

Dear EpiData list. With the latest release of the EpiData Manager and EntryClient some changes were made to the format of datafile. Therefore the test files from today contains an updated sample file. Please delete older versions. During the development phase of Manager and EntryClient changes to the XML structure should be expected, e.g. the latest extension specifying timed recovery backup. As soon as the first public release is available for routine usage we will make sure that coming versions can read all older files. But during the developments this will not be the case. In the meantime we will provide a working sample file for each new test version such that it is possible to see the capabilities of the program. The exe files uploaded today are the same as yesterday, except that the sample file is contained. Kind regards, Torsten Bonde Christiansen.

New Manager and EntryClient test version released.
by epidata-list＠lists.umanitoba.ca 07 Oct '10

07 Oct '10

Dear EpiData list. As of this morning (danish time) new test versions of both EpiData Manager and EpiData EntryClient have been released on our testing website: http://epidata.dk/testing.php Please be aware that the back-end code for the testing website have been changed, so if you experience any problems with downloading the files please report directly to me on: tc "at" epidata.dk The major changes for these version are: * A "timed recovery backup" system has been implemented in the EntryClient. At a given interval (this is set in EpiData Manager within "Project->Settings->General") a recovery backup is save to disk with the same filename as the project file but with an additional extension ".bak". On a clean close of the program this file is deleted, hence a regular user should not notice the existence of this file, but if the program crashes unexpectedly the file will remain an upon trying to load the original file, the user is informed that a recovery file exist and advised to load the recovery file. * In addition to the "timed recovery backup" system, it is no also possible to specify that a complete backup of the project file is taken on close/shutdown (again, this is specified in EpiData Manager). The backup is NOT used as part of the timed recovery system, hence the used is not noted of the existence upon loading the original file. This is merely meant as a "daily backup" feature, that gives the user the possibility of storing backups of the daily work. In the future this option is probably going to be a lot more configurable by the manager, but for now the original file is "just" stored with the same filename, but containing the date of saving. * Both Manager and EntryClient now has a feature that allow for checking on-line if a new version of the program exists. This naturally requires an active Internet connection, but if no such exists a non-fatal warning is given. * In addition to the above a small number of bug-fixes and speed improvements have also been implemented. Kind regards, Torsten Bonde Christiansen. EpiData Association.
