14 Nov '16

Dear Epidata Team, I was wondering if epidata entry can be used in mobile devices like ipad or android tablets. I noticed someone asked about this in 2012, but i couldn't find an answer for that subject. Is it possible? Thank you very much for all your work. DD Doris Durán Santiago, Chile

problem with XML version 4
by EpiData development and support 12 Nov '16

12 Nov '16

Dear Epidata team! I tried to open a project in manager but got this error message: "PROJECT HAS INCORRECT XML VERSION! MAX SUPPORTED XML VERSION:3 PROJECT XML VERSION 4" I then looked at the file in an XML editor, the header indicated version 4: <?XML VERSION="1.0" ENCODING="UTF-8"?> <EPIDATA XMLNS="HTTP://WWW.EPIDATA.DK/XML/2.1" XMLNS:XSI="HTTP://WWW.W3.ORG/2001/XMLSCHEMA-INSTANCE" XSI:SCHEMALOCATION="HTTP://WWW.EPIDATA.DK/XML/2.1 HTTP://WWW.EPIDATA.DK/XML/2.1/EPX.XSD" VERSION="4" XML:LANG="EN" DATESEPARATOR="/" DECIMALSEPARATOR="," TIMESEPARATOR="." CYCLE="56"> I tried the change the header to this (taken from an earlier version of the project which was working): <?XML VERSION="1.0" ENCODING="UTF-8"?> <EPIDATA XMLNS="HTTP://WWW.EPIDATA.DK/XML/2.0" XMLNS:XSI="HTTP://WWW.W3.ORG/2001/XMLSCHEMA-INSTANCE" XSI:SCHEMALOCATION="HTTP://WWW.EPIDATA.DK/XML/2.0 HTTP://WWW.EPIDATA.DK/XML/2.0/EPX.XSD" VERSION="3" XML:LANG="EN" CYCLE="56"> This resulted in a new error, although I managed to open the project. But the project did not contain all CRFs and no data... New error message: "LIST INDEX (0) OUT OF BOUNDS.PRESS OK TO IGNORE AND RISK DATA CORRUPTION [....]" As this is a real lifr project and I had to be able to carry on, I solved the problem by copying the records from the bad file back into an previous project file by using an XML editor. It then worked fine. I noticed only one difference at the end of the bad file, some log lines. Hope this can help the project. I am using the 2.0.13.64 64 bit Win version of Manager and 2.0.10.26 of the Client. We had the same problem on the Mac Version Best regards Jonas Malmstedt -- ------------------------- Jonas Malmstedt Överläkare, M.D, Ph.D. - Consultant vascular surgeon Section for vascular surgery, - Department of Surgery Södersjukhuset - 118 83 Stockholm - Sweden ORCID ID [1] http://ki.se/en/kisos/sosvasc [2] http://ki.se/people/jonmal [3] Phone: 0046 (0)8 616 2893 email: jonas.malmstedt(a)sll.se Links: ------ [1] http://orcid.org/0000-0002-2758-9623 [2] http://ki.se/en/kisos/sosvasc [3] http://ki.se/people/jonmal

Problem with change of name of valuelabel and valuelabels for type
by EpiData development and support 11 Nov '16

11 Nov '16

Dear Epi-Data team! If you intend to change to a new Valuelabel (eg change name of the valuelabel and add a new value) in manager and do this via "Edit" and changes the name of the old label and add a value, then all variabels in the project get the new valuelabel. You have to do like this: "Edit", choose "none", then "Apply". Then choose "New" and make the new valuelabel. But when doing this I get "Access violation" error message. I think the access violation error is a problem with the type UPPERCASE which do not allow that you create valuelabels.

If-then skip function
by EpiData development and support 10 Nov '16

10 Nov '16

Dear Epidata users, Apologies if this has been asked before but I could not find the answer in the archive. I knew how to do an IF and THEN command in the old version of Epidata. I am now using version 2.0.8.56 and am stuck. I can perform a skip based on the field I am on (in 'field 'properties' in the 'jump' tab). But how do I do a skip based on a previous field? i.e. at the end of a section entering personal information I want to skip to one of several subsequent sections depending on what was entered in one of the early fields of personal information, not the last one in the section. I hope my query is clear. Thanks, Suzanne

An issue of lower vs. UPPER case naming, terminology change warning and other plans of implementation
by EpiData development and support 02 Nov '16

02 Nov '16

Dear All In the decisions of development we need to focus at all times to : a. simplify interface, b. create structured and easily understandable terminology c. adaptation to many combinations of users, computers and local language implementations of texts etc. In order to do so we will attempt to be more precise in terminology 1. We plan to use these definitions: project: all information contained in a given epx file dataset: contains all variables in a single entry form observation: is the data unit observed (formerly called a record) variable: contains a single data entity (formerly sometimes called a field) variable label: the descriptive text for a variable value labels:define legal values and gives a text for each value Any legal value can be given the "missing" status and exported as such If you have related data (e.g. house -> person -> visit) each of these will be a dataset containing a number of observations recorded in those variables present in a given dataset. 2 We will implement a "non case sensitive" principle. That is v1 and quest1 will be the same variables as V1 and QUEST1. H1 and h1 as a header text will be the same. But obviously the variable labels and header text can contain as well local language characters and any upper/lower case text. 3 EntryClient will get a "save as" possibility in the file menu, since sometimes we have experienced that a network drive was lost during entry, e.g. Z drive: - then any changes was lost since last save because there would also be no timed backup residing on that drive. 4 We will consider whether to implement a timed backup up principle in manager, just like there is one now in entryclient. If connection to the network is lost or the software brakes down, the timed backup file can be used after restarting Manager. 5 We will implement a missing value definition for dates and jumps based on date values. Please comment on the these aspects if you have ideas, suggestions, find the terminology confusing or have other examples of different terminology across Analysis, EntryClient and Manager. regards Jens Lauritsen EpiData Association, Denmark

New Manager Version (2.0.13.64) due to blocking bug -
by EpiData development and support 02 Nov '16

02 Nov '16

Unfortunately the version (2.0.13.63) of Manager had a bug in Windows, which we did not catch before release. Therefore please download and install the version 2.0.13.64, which was just uploaded. We will gradually be more strict in applying quality assurances before release, but sometimes this could result in 1-2 weeks delay of a bug fix version due to limited staff. Users who wish to assist in the quality assurance release program can send us an e-mail on info at epidata.dk We apologize for the inconvenience incurred by this and thank Mr Thambo for the reporting. Regards Jens Lauritsen EpiData Association, Denmark

Dear List. A new version of EpiData Manager (2.0.13.63) has been released for public use. The new version contains a fix only related to linux, where moving fields no longer worked correctly.

Is there any file size limit in Epidata Analysis 2.2.2.183
by EpiData development and support 29 Oct '16

29 Oct '16

Dear Jens,                       Thanks for the quick response. It was heartening to know that Epidata development is progressing. Keep up this good work for the public health cause.Regarding the record limit issue;I tried correcting the wrong dates and that did not help. I tried reading the file without date variables, still the same problem persisted.  However, I extracted 3 variables of interest and wrote a separate file of 4.9 Mb. Original file size is 9.2 Mb. This extracted small file was easily read by Epidata Analysis.Just a small point about Epidata Analysis.If there is adequate RAM (4 Gb) and hard disk space (1 Tb) on the PC, does Epidata Analysis have any file size limitation? Can size of the rec file be the problem here?With regards,Dr. Shavinder

Status and strategic decisions for development of EpiData Software
by EpiData development and support 28 Oct '16

28 Oct '16

For all users of EpiData Software I am writing today to explain some changes you may notice in future list postings from me. Due to regulatory demands in Denmark there is a need to formalize some of the development strategies, including how the EpiData list is used to support development. Some of the emails from me will have a form where statements made are understood as accepted unless further debate gives reason for changes. Any comment or indication of opinion is welcomed at any time. If no major comments are given within 5 days the paragraphs will be formally understood as accepted by the user base. I want to reassure you that there will be NO information given to anyone regarding who is on the discussion list, anything you say here or otherwise express in relation to development or preference in strategy. In the formal constitution of the Association this is formulated as stated below my signature. There will be a continued division of decision making in EpiData development in which the roles are: a. this EpiData-List: discuss principles, decisions, practical implementation, bug removal, questions on specific aspects etc. b. the core group: Definite strategic decisions including those with financial implications are placed here. The core group is comprised of those giving major input to development. Names are indicated in the section "Particularly Active" in the "Friends of EpiData" section on the credit page of the main webpage. c. specific implementation: These are ultimately made by me and Torsten Christiansen, who is assuring sound software principles. At the final level I am legally responsible for all decisions taken, but it is important that the whole user base is informed of the principles. Best regards to all Jens Lauritsen, MD, Phd. Initiator and Coordinator EpiData Association, Denmark ------------------------------------------------------------------------------------------------------------------------ Formal extract: Decisions on dissemination and development strategies is taken in an open discussion on the EpiData list, which is open for all users. Specific power users from the user base will be added to a group of core decision makers (the board), who can sign account balance’s and grant signing rights to one or more persons in the core group in relation to payments and salaries. The board is guided in the larger decisions by the ”Friends of EpiData” – an international collection of experienced persons within EpiDemiology, Public Health and Community Medicine supporting the aim of the EpiData Association. Updated lists of names are shown at www.epidata.dk/credit.htm. To ensure broad support in development decisions and strategies all major directional plans will be made publicly available on the EpiData discussion group list, which is open to all users. Such plans will be clearly formulated as such with proper timelimits for commenting and possible changes.

Is there any record limit in Epidata Analysis 2.2.2 (ver 183)
by EpiData development and support 28 Oct '16

28 Oct '16

Dear  Jens and Epidata Team,                                                       There ia prolonged silence on the list. I hope everything is fine and development is progressing.I have a unique concern. There is a flat file of classical Epidata Entry 3.1. The number of records is 93425. I am using Epidata Analysis 2.2.2 (ver 183).  Epidata Analysis does not read this file.Only message I get is “Loading data D:\EpiData\PH\D.REC, please wait...The indicator below is green. When I convert this “rec file”  to  “dbase file” using classical Epidata Entry 3.1,  the converted dbase file is easily read by Epidata Analysis. (However it adds decimal and two zeroes to the numeric data.My question is; Is there any record limit in Epidata Analysis 2.2.2 (ver 183)?With regards,Dr Shavinder
