How to analyse for outcomes at specific periods during follow ups
by epidata-list＠lists.umanitoba.ca 15 Nov '11

15 Nov '11

Dear ALL I have a relational (Epidata entry) data base which I have data for over one year follow up of patients. I would like to analyse in Epidata analysis and check the Blood pressure, blood sugar readings......at every six months follow up for each patient since they were enrolled. How do I get to select six month, twelve month....visits for each patient form their date of enrollment. ( in my database I have var: entrydate at registration and visitdate on each visit) Thank you Walter

Double entry verification
by epidata-list＠lists.umanitoba.ca 10 Nov '11

10 Nov '11

Is it possible to use the Double Entry Verification tool on a relational database? The related REC files are: * Infant health diary.rec (the "Parent" file), and * Infant health diary weekly record.rec (the "Child" file) I created the double entry databases: * Infant health diary_dbl.rec, and * Infant health diary weekly record_dbl.rec In "Infant health diary_dbl.chk" I edited the code for the relate command so that the double entry file is linked: RELATE idchild "Infant health diary weekly record_dbl.rec" When opening "Infant health diary_dbl.rec" for entry, I'm not given a warning stating that EpiData is in double entry verification mode. Is there something else I need to do to make this work? If not, I realise I can set up a second relational database and check for inconsistencies once all the data's been entered.

RE : EpiData-list Digest, Vol 97, Issue 7

Hi, A response to Réjean, I did not experience your "out of memory" problem, but I had the "Unable to open the file. An unknown error occured" one several times (because of ranges in DMY date fields, see my message on the list). In this case, you can edit the epx file in wordpad or notpad, and delete the wrong lines, supposing you can identify then (possibly lines concerning value labels in your case). Another solution is to backup files often, so that you don't have to start all over again each time. Sorry, this won't give you the solution of your problem, but maybe will help you keep your patience while testing the Manager! Confraternellement, Pascal Thibon, MD, Epidemiologist CHU Caen France

EpiData Manager bugs - Request for assistance - Follow-up.
by epidata-list＠lists.umanitoba.ca 08 Nov '11

08 Nov '11

Ma 08 nov 2011 To Torsten Bonde Christiansen: Dear colleague, As asked, the EpiData Manager version that was downloaded from the test web site on october 26 2011 is: Program Version: 0.8.8 r371 Core version: 0.8 r475 FPC Version: 2.4.4 Platform: i386-Win32 No installation was needed; it was simply copied on the desktop (bureau in french) by one of our IT peoples; should it be installed in a specific répertoire (folder)? It's a simple exe file that run after cliquing on the EpiData Manager icon. If of any use for you, the portable PC I use is a lenovo T400 running on Windows 7 and 64 bits (bibites in french?). If I can pass over those major bugs, especially this "out of memory" one, I could test this software and began my learning curve at the bottom. This "out of memory" bug remember me the old "runtime error" or "stack overflow" of the old Epi Info DOS; however, in the Win environment, it seem to be a fatal problem for the files... One of the things I also need to know is how to create something similar to the chek command COMMENTLEGAL (with codes and associated values). Many thanks for your support.

encryption fields in EpiData
by epidata-list＠lists.umanitoba.ca 08 Nov '11

08 Nov '11

Greetings, I am implementing an application that has to import .REC files, including encryption fields. EpiData documentation says the encryption used is AES/Rijndael, and nothing more. That information is not sufficient, unfortunately. Therefore I would like to ask: (1) What is the keylength used? (2) What is the cipher mode of operation used? (3) If the cipher mode is ECB or CBC, what kind of padding is used? (4) Is an initialization vector or salt used? (I guess none, since EpiData creates the same encrypted text in the first line of the .REC file, whenever the same password is used). Probably these questions should be answered by a technical person, i.e. EpiData developer. Thank you in advance, Theodore Lytras

Epidata Manager tests
by epidata-list＠lists.umanitoba.ca 08 Nov '11

08 Nov '11

Bonjour à tous ! I have tested ED manager and entry client. It seems to me that this new version works fine and already looks very "professional". I only found 2 bugs (I hope this is the right place to report them) : 1/ ranges in DMY date fields : programming ranges for YMD date fields works fine, but for DMY date fields, the project will refuse to open in ED Entry Client. I only managed to open it after editing the xml file and erasing the lines containing the date range specification ; 2/ crash when trying to edit value labels of boolean fields Althought it's quite illogical, I tried to edit value labels for a boolean field. This caused an immediate crash 4 questions : 1/ I would like to program conditionnal jumps (in field X : jump to fiels Y if field Z=1). In previous versions, this was possible with AFTER ENTRY in chk files. 2/ It would be very useful to test a data structure directly in ED manager (CTRL-T in previous versions) 3/ In ED Entry client: at the end of a record, if you answer "NO" to "Save Y/N", all of the fields are cleared 4/ I work with sas for advanced analysis. Who do I export from ED ? Thanks again for this great software! Pascal THIBON, MD, Epidemiologist CHU Caen France

Missing example and pdf in linux packages
by epidata-list＠lists.umanitoba.ca 08 Nov '11

08 Nov '11

I just want to inform, if you downloading the Linux packages from the testing area the example file and pdf are only symbolic links and not the documents itself. By the way it seems that the Linux versions are not running under Ubuntu 11.10 due to changes in GTK libraries. I will try to use it on another system later on.

EpiData Manager bugs - Request for assistance.
by epidata-list＠lists.umanitoba.ca 08 Nov '11

08 Nov '11

Lu 07 nov 2011 This message was sent to epidata-list(a)lists.umanitoba.ca two days ago, but only the tittle was published in the Digest; for this reason, I'm sending it again, with the added mention "Request for assistance". Dear colleagues, I'm exploring EpiData Manager for creating a very simple data entry form. Here is the major bugs I encountered: - I can't save the epx file outside of the "bureau". - Each time I try to use the field value label editor (adding a new value) the system crash with an error message "out of memory"; this jump me out of Manager and when I try to open the existing epx file I can't and the following error message is displayed: "Unable to open the file. An unknown error occured". The file can't be recovered (I recreated a new epx file, but I lost all of them [including my patience after 10 trials]). - Displacing a field on the screen is somewhat erratic; the question beside the field seems to go farther away each time I try to correct the alignment. - Creating a new section box is problematic; I keep creating boxes over and over again and it's impossible to go back or to delete the empty boxes. Giving those bugs, I'm unable to create a project. Is there a manual explaining a little bit more how to use this new interface? The short orientation document is too general to be really usefull for a novice. The concept is interesting and I would like to test it, but I fly in the dark or in the mist actually.
