Serious bug identified (only in a special type of projects with related dataforms) - update to new EntryClient

Yesterday - We have identified a bug which have created incorrect data in a certain situation . therefore - an updated EntryClient version has been uploaded (EntryClient 2.0.9.25) today. The change is due to a serious bug in RELATED dataforms. With single dataforms there is NO problem. For most projects with related dataforms the situation is: 1 New observations are added with unique key fields (say "project id"+"date of visit") 2 key values are never changed. Then you have NO problem and your data are correct. But if a project has: a. related set of dataforms (main + one or more child dataforms) b. the key contains MORE than ONE field. c. you have edited (changed) values in one of the key fields after entering records "above" a child form d. child records for more than one observation have the same value in a key field which was edited at a higher level AND you can say YES to all of a+b+c+d there is reason to check your data. If there is doubt for a given project you are welcome to contact us by mail at "info at epidata.dk" for further advice. The situation arose when we changed a flat file structure to a related structure. We split the flat file to four subfiles and imported the data into a related structure. As a first step gave one of three fields of the key the same value, whereas obviously the combination of three fields was unique. Following import this was correct, but after changing all 1000 records we realized the problem. We apologize very much for the inconvenience this might incur, but do hope that you will continue to report any strange behaviour. Only by meticulous observation can we find such unfortunate bugs. regards Jens Lauritsen EpiData Association, Denmark

RELATE-aware analysis
by EpiData development and support 17 Aug '16

17 Aug '16

Hello. I'm using EpiData 3.1 on windows 7 to enter data into a set of RELATEd .rec files: HNPforms.rec (these are visits to households; data about the building) Adults.rec (data about the adults living in the household) Children.rec (data about the children living in the households) Each visit to a household has a unique ID number, and that number is propagated to a field in each adult's and child's record. There can be multiple visits to each household, so an indicator of initial visit versus revisit is included in HNPforms.rec and is propagated to the records for the adults and children living in that household. Using EpiData Analysis, is there a way to "connect" the child records and the adult records to their own household records, for purposes of analysis? Merging on the unique ID number, so to speak. Thanks. --Chris

Upcoming updated software versions next week
by EpiData development and support 12 Aug '16

12 Aug '16

About a month ago users experienced unexpected problems with the most recently uploaded public version. The problems were basically very grave and would not allow various aspects of core functionality, e.g. working with value labels. Due to the documented problems we have now implemented a new test principle for EpiData Manager and EntryClient, which will be followed before public release. The tests are structured in a spreadsheet format and performed by local staff here in Denmark (public health students). Based on the tests performed we have found un-disclosed errors, which is a "proof of concept" of the idea to pre-test thoroughly before public release. In contrast to relying on unstructured testing. Early next week we will therefore release new versions for production use and also the spreadsheet, which documents what we do test before release. For coming releases I therefore suggest that users assist in the testing. You may then receive pre-release copies of the software, such that the overall testing can be thorough. Recent experience has shown that some combinations of operating system versions and types (32/64bit) etc have given problems that we have no possibility of neither catching or solving without the help of some of you. In short therefore: be prepared to download new production versions of EntryClient and Manager next week. Regards Jens Lauritsen EpiData Association
