Dear Jens,How many parent child forms can be related in Epidata Managerand EntryClient?I have noticed that following sequence of forms do relate upto 3levels only.Family Form-> Eligible Couple Form-> Under Five Child Form-> Growth Monitoring FormClassical Epidata Entry could relate upto 4 forms.Is there any technical limitation to number of "child"forms whioch can related to main and subsequent child forms?With regards,Dr. Shavinder

Dear all, I have scanned the new Windows exe file "setup.all.4.4.3.1.win.exe" with Kaspersky and found no issues. Kaspersky also provide a free service to whitelist software on https://whitelisting.kaspersky.com/whitelist_program. Furthermore McAfee Endpoint security reports the webplace epidata.dk safe to use and finds no threats when scanning the file setup.all.4.4.3.1.win.exe. However Microsoft Explorers "SmartScreen-filter" reports the program setup.all.4.4.3.1.win.exe with a generic security warning "This executable could harm the computer" and "SmartScreen-filter rapporterade att det inte är vanligt att det här programmet laddas ned och att det inte är signerat av utgivaren" translated to "The SmartScreen filter reported this executable to be an unusual download and the file is not signed by the provider". This is described in https://support.microsoft.com/en-us/help/17443/windows-internet-explorer-sm… and maybe creating a certificate could solve this IE problem? (https://docs.microsoft.com/en-gb/windows/uwp/packaging/create-certificate-p…) I hope this can be of some help. Seems though tat the download issue is restricted to Internet Explorers SmartScreen filter.

Epidata Data entry
by EpiData development and support 27 Sep '18

27 Sep '18

Hello, I have Downloaded and installed Epidata Entry version 4.4.2.0.i386.darwin.dmg on my MAC - from 04. July 2018. But when I double click on a REC file or a QES file I get an error. Access error. When I open Epidata Entry and try to open a REC or QES files, they are greyed out. I am using MAC OSX Sierra. Is this a compatibility issue? Venlig hilsen/Kind regards Antonio Sylvester antonio(a)au.dk

new EntryClient - bug fix of relate and blocking in long entryforms.
by EpiData development and support 06 Jul '18

06 Jul '18

A new version of EntryClient was uploaded yesterday (v 4.2.2.0), Get it from: http://www.epidata.dk/download.php which fixes these two bugs: 1. In a project with related datasets, e.g. family - person - visit - laboratory tests There was a bug which could lead to more than the specified number of observations in a given file with the same key. This bug has been removed 2. If you had very long project and did a showing during entry of the defined value labels, then the EntryClient would freeze due to misplacement of the "value label window" outside the boundaries of the current screen (in windows). We have thoroughly tested all the software for possible virus and found NO indication of any problems. If you find new bugs or problems, please discuss on this list. best wishes Jens Lauritsen EpiData Association Denmark

message to all EpiData users - we have received reports of an important potential problem
by EpiData development and support 20 Jun '18

20 Jun '18

We have received two independent messages of a potential virus/viral threat with the latest EntryClient in the Windows version. (From Sweden and Switzerland) The programming and compilation of ALL EpiData software is done in Linux and we have NOT changed any of the programming tools from the latest to the previous version of EntryClient. Where we work these problems have not occurred, so it seems to be dependent on which particular version of the anti-virus software is blocking the function of EntryClient. We are reasonably convinced that the problem is some similarity of internal code with a known virus or trojan. If our development system had been infected, then this would also affect previous versions. To be sure of this we will obviously spent some time to look into the problem in collaboration with the reporters. AND quite soon return with a solution. (In the meantime I would personally mark in my virus software the EntryClient as not-infected - if that is possible, but it is obviously up to you. The reason being that we have not changed anything here) Should you experience such problems please write an e-mail to info (at) EpiData.dk - following solving the problem we will then contact you directly. best wishes Jens Lauritsen EpiData Association Denmark

Re: [EpiData-list] EpiData-list Digest, Vol 172, Issue 4 - McAfee wrong virus detection
by EpiData development and support 19 Jun '18

19 Jun '18

Dear all, This refers to McAfee Endpoint security ver 10.5.3.3178. This program is forced by my employer. I get a warning when downloading the exe file and when running manager/client. This applies both to the old Epidata version from 2007 and the new. There has been NO signs of malfunction or infection. I believe strongly that this issue is not related to an actual virus threat but rather that McAfee detects all non-standard programs. The logs from McAfee follows below (mostly for the Epidata team): Ryktet för programmet EPIDATAMANAGER.EXE är Okänt, vilket är under den konfigurerade inneslutningströskeln.

Major news : Rewritten EpiData Analysis v1.0, updated versions of EpiData Manager and EntryClient
by EpiData development and support 14 Jun '18

14 Jun '18

For all EpiData Users. Today we have taken a major step forward with the release of a rewritten EpiData Analysis in version 1.0 and version 4.4 of Manager and EntryClient. The ability to use relational structures, encryption, user logging and other complex aspects has been implemented. We do hope that users will find this an important step forward. It will not be long before further functionality is available in Analysis. In the test versions we have already a functional aggregate, and tables is next step. Get the new versions for Linux, Mac and Windows from: www.epidata.dk/download.php Read the introduction documents for each software from the help menu after you start the software. As always when versions of software change be particularly critical to ensure backup copies of all data in a secure place before updating. Analysis is ready as v1.0 in terms of: - read project files (epx/epz including encrypted files), but also Stata dta, CSV, Rec+Chk files) - data management - combine files (merge, append) - saving, exporting and archiving data files (epx, dta, csv, ddi-3.1) including metadata - frequencies, count, means - validation of files and other aspects For Windows there is a combined installer for all three types of software - regardless of whether you have a 32 or 64 bit computer. All three EpiData software tools use an updated data file structure. Once you have read and saved an epx file it will not be possible to open it in a previous version of the software. So make sure to update all copies of the software that you are using, e.g. if you have local data entry. All example files are now located in a specific user specified folder, which you may choose during installation. In that folder example pgm files for analysis and pdf introduction documents are contained. Observation: on some restricted systems (eg. in a hospital) the user might not be asked to decide the folder position during installation or other user specifications. We cannot apparently control the installation completely. As always discuss function on this list and contact us in case of serious or reproducible data errors occurring due to system functioning on info (at) epidata.dk We wish to express as well thanks for inspiration and help from in particular Jamie Hockin and Hans Rieder, but also received funding from The Union (DFID fund) and other funding bodies.
