EpiData and Apple Mac

Good day, In our University we run a course on-line and students learn how to use EpiData as well as Stata during the course. We encountered a problem with the students who use Apple Mac computers and who are using Catalina OS. It appears that EpiData does not run properly in Catalina environment. They can download and install a beta version but that does not allow saving, for example, or export to Stata; so they are unable to submit assignments requiring the preparation of questionnaires, data entry or export to Stata. It affects about 20 of our 600 students. Does anyone have any solution to suggest?

New test version of EpiData Software (Mac working and dialogs in Analysis)
by EpiData development and support 26 Apr '21

26 Apr '21

Dear all A new test release has been placed on www.epidata.dk/testing.php The changes will be released as public version after implementation of a few more changes and tests. Users are invited to test the following new features and improvements: - but remember as always to work on test data and copies of projects. Major new feature in Analysis: Dialogs for statistics A visual form which will create the command - like in Analysis ClassicSpeed of reading projects has been improved EntryClient, Manager and Analysis work in Mac (64 bit - latest OS) A number of bug-fixes and internal clarifications to manage definitions of missing data and tables have been implemented. Most of this is important improvements, but should not be visible to the user, apart from reading of files being much faster. One of the difficulties is to ensure correct implementation of procedures for encryption, user control of entry (logging) and the way the operating systems control access to the encryption libraries. Increasingly in many organizations user have only restricted access to their own computer making it difficult to write software - without paying licenses to e.g. Microsoft and Apple. The test versions are provided as zip/tgz compressed files. Make sure that you unzip all content with maintained folder/directory structure Please comment on the list if you have problems/suggestions or experiences with the updated versions. One note is that after unzipping and opening you should resize the dialogs in Analysis if you have a Mac computer. Otherwise some of the content is not sufficiently intuitive to use (we are working on that). As always the changes were made in a collaborative effort of Torsten B.Christiansen, Jamie Hockin , Hans Rieder and I. Torsten does the main software desing and programming and Jamie added important aspects of Mac function and dialog implementation. best wishes Jens Lauritsen EpiData Association Denmark

Child form unicity bug
by EpiData development and support 13 Mar '21

13 Mar '21

Hello, First, I would to thanks the Epidata team for the great job done so far. Recently, in a database with a main form and several child forms (single or repeated), we observed at the end of the study several duplicate forms for several patients. This can happen on a 1 to 1 relationship or on a 1 to many relationships. We checked the properties of all datasets. They have been properly established to ensure that each record is unique. We have performed some tests to reproduce the issue and found that the issue occurs when a key field is exited with the mouse, or when a form is exited using the mouse to choose a new form to fill in the left panel of the screen instead of leaving the form with the last filled field. When this happens, the user can browse the forms and enter a duplicate visits without warning. Under these circumstances, the "Save Form" dialog box appeared twice. These bugs can be reproduced with the child-bug.epx (joined file) database using the following procedure: Add a new patient Fill out the main form with a new patient: Patient n ° 45 Age: 2 years Height: 90 (do not use Enter key) After typing 90 on the keyboard, use the mouse to select the inclusion data form. After this action, the "Save Record" dialog box appears twice instead of once when the Height field is exited with the Enter key. Once the focus is on the inclusion form, enter today's date and weight e.g. 12 kg (do not use the enter key). After typing 12 on the keyboard, use the mouse to select the Visits form. Once the visit form is displayed, select the inclusion form again. Instead of displaying the data entered previously, the form is empty and the completed forms counter is zero, add the current date and a weight. If you repeat this operation several times, you can complete more than one form. The number of child forms filled is only "correctly" displayed when the patient is exited and selected again. I hope these information will help to solve the problem.

Thank you for your response. Example with my own file. .freq castem; castem ----------- N ----------- 1 153 2 150 3 632 ----------- Total 935 ----------- .select castem<>3 do; Selecting, please wait... (303 of 935 selected) .begin; ==> No operative (idem begin without < ; >) ERROR: Line 1: Syntax error at pos 7: ERROR: Unexpected end of line! Perhaps a ";" is missing? .freq castem; ==> no selection... castem ----------- N ----------- 1 153 2 150 3 632 ----------- Total 935 ----------- .select castem=1 do drop data; ==> objective : keep codage 1 Selecting, please wait... (153 of 935 selected) (153 observations dropped) .freq castem; ==> Selection code<> 1 (link avec drop data ?) castem ----------- N ----------- 2 150 3 632 ----------- Total 782 ----------- And an another (and last) question : how to delete the current selection? Thank you. Bernard Branger, Nantes, France

New analysis
by EpiData development and support 06 Feb '21

06 Feb '21

Hello, For training, I'm trying to understand the new version of "Analysis". A few comments : - The command "freq var ! r;" (as shown in the guide) doesn't work, but "freq var ! pr" is OK. Strictly speaking and on the educational plan, the percentages presented with "freq" are in columns : "freq var ! c;" or "freq var ! pc;" would be more logical. - To select a part of the file, I noted, (as an example for a frequency) the command "select (var1 <3) do freq var2 ! pr;". Should we repeat with each command "select (var1 <3) do"? Is there a way, like the old "select", to select part of the file for further commands? - The command (example) "select (var1 = 3) do var1: = 2;" is quite complicated compared to that "if ... then ...." - How to create a new numeric variable with 3 digits and 2 decimal places? As in the old "define var ###. ##"? - When will the "regress" commands and the graph commands (including scatter with a regression line as in the old "Epi-Info" ...? Thank you for your help.

Re: [EpiData-list] Epidata 4.6.0.4 SPSS-Export
by EpiData development and support 15 Dec '20

Dear Michael, thank you for this hint! That makes things much easier. If someone nevertheless needs it, I attach a spss syntax, that produces a list of string variables in the datafile and than deletes all leading and ending quotation marks (the first and the last character) in these string variables. It can be included in the spss import syntax.

Epidata 4.6.0.4 SPSS-Export
by EpiData development and support 15 Dec '20

15 Dec '20

Dear all, I have a little problem with the SPSS-Export of the Epidata-Files. When you export string variables, you can specify the variable delimiter (e.g. "|") but not the text delimiter. The result is a csv file, that is imported in SPSS with quotation marks at the start and the end of every string variable, even if the variable is empty. I found no way to delete these quotation marks during the spss import process except with a quite complicated macro. Is it possible to change the SPSS export? Kind Regards, Juergen Spiegel -- *********************************************************** Freiburger Institut fuer angewandte Sozialwissenschaft e.V.
