This problem usually arises because a file has been edited and some record lengths changed or from the introduction of some random characters with a disk error. I have always been able to reconstruct .rec files using a plain text editor like the old Windows Notepad. Even better is a programmer's editor (there are many) that can identify the end of each line in case you have a line with more than 80 characters in the data section (e.g. some spaces beyond the !).

New test version of EpiData Manager - (v 1.3.0.5) - print dataforms
by epidata-list＠lists.umanitoba.ca 25 Sep '12

25 Sep '12

Dear List Today we have released a new exprimental test-version of EpiData Manager (v 1.3.0.5). The new version is available for download on our testing website: http://epidata.dk/testing.php#alpha In this test version we have changes the printing routine to support printing directly to a printer, rather than to SVG files (vector graphics). In addition to support printing a number of minor bugs have also been fixed. The full list of changes can be found here: http://epidata.dk/epidatamanager.changelog.txt The next test release for the project will contain printing ability for the EntryClient Unless the testing reveals problems, which cannot be solved easily - the official version for real projects will contain the functionality in the current testversions within some weeks. Announcements will take place here on the list. Following the release of the next official version for real projects an announcement will be made regarding the planned features for the coming six months. Kind regards Torsten Christiansen Jens Lauritsen EpiData Association

Help with epidata manager
by epidata-list＠lists.umanitoba.ca 15 Sep '12

15 Sep '12

Dear Jens Lauritsen, EpiData Association Denmark I am the co-ordinator of the Clinical Epidemiology Unit of my medical college in South India. We teach research methods to post graduate students and have been teaching epi-data for a few years, with a lot of positive reviews from students. We have now been trying out the epidata manager that you have introduced.We thought it would be a good idea to switch to teaching this to our residents rather than the earlier epidata. In this context, i need your advice 1. Is epidata manager ready for use by students-ie is it still in testing? 2. We seem to be running in to some trouble with using epidata manager-Sir, do you have a detailed user manual or online presentations that we can access to learn the use before teaching I look forward to your early reply I want to thank you again for this brilliant effort-many in developing countries with resource constraints are blessed by these efforts Thanking you regards Dr Thambu David S Professor and Head Medicine Unit 2 Christian Medical College, Vellore 632004, India

Fwd: Ny Manager

Dear List Today we have released a new exprimental test-version of EpiData Manager (v 1.3.0.4). The new version is available for download on our testing website: http://epidata.dk/testing.php#alpha Please challenge this test version. The following description is rather short, test and see whether you find interface and function intuitive, and specific aspects with correct function. . The main new design feature is: * Completely rewritten dataform designer * Moving, selecting and replacing fields on the dataform is easier. * Select multiple fields, texts and sections. * Changes to Copy, cut & paste. - Paste will happen at current position of mouse pointer. * Preliminary Undo/Redo support. This is so far limited to dragging and sizing of controls. * Importing data and structures is combined into the same funtionality. New export formats (CSV, SPSS, SAS) * Export (printing) to SVG file format, (click on tool in tool bar) which can be read by e.g. Inkscape (see inkscape.org) of dataforms * View data * Encryption of project data (headers are still human readable) * Key unique including testing of status * Prepare Double Entry and Validate Double Entry functionality * Reports may now also be output as Text rather than HTML. Kind regards Torsten Christiansen Jens Lauritsen EpiData Association

> > > >sort ID PERIOD POFFSET >gen MARK=1 >if (ID = ID[-1]) and (PERIOD=PERIOD[-1]) then MARK = 0 This is a great approach. I just want to add something. According to my understanding, this would make MARK=1 for the records with the smallest number of one set of ID and PERIOD. But it does not necessarily mean that the record with MARK=1 would be closest the expected date. In this example, > Each period I select (M3, M6, M12...) I give an allowance of + &- 10 days. > (e.g. for M3=90 days from the day of enrollment, I select between day 80 > and day 100). This is because patients did not always respect their > appointment dates. for some reasons, if the patient came at 81 and 93 days, PERIOD would be -9 and 3 respectively and the record with PERIOD=-9 would be selected (MARK=1) which is not desirable. To avoid this situation, we just need to neutralize the minus sign of POFFSET by doing this before sorting ID PERIOD POFFSET. So, I would suggest the following command: if POFFSET<0 then POFFSET= -1*POFFSET[_n] sort ID PERIOD POFFSET gen MARK=1 if (ID = ID[-1]) and (PERIOD=PERIOD[-1]) then MARK = 0 Best wishes, Zaw > Message: 5 > Date: Mon, 27 Aug 2012 08:23:24 -0400 > From: epidata-list(a)lists.umanitoba.ca > Subject: Re: [EpiData-list] Epidata analysis > To: epidata-list(a)lists.umanitoba.ca > Message-ID: <BLU0-SMTP250E7B96809BAD9A83BDABFDA20(a)phx.gbl> > Content-Type: text/plain; charset="windows-1252" > > The approach to this would be: > > - create the new variable that identifies period (I'm not sure why you use > more than one) (PERIOD) > - create a new variable that equals the number of days between expected > and actual visit (POFFSET) > - SORT the data on patient ID, PERIOD and POFFSET > - create a new variable to mark the first record you find for a given > patient and period (MARK) > You do the last two steps like this: > > sort ID PERIOD POFFSET > gen MARK=1 > if (ID = ID[-1]) and (PERIOD=PERIOD[-1]) then MARK = 0 > > MARK will set to zero for the second visit for any patient in a period > (because ID and PERIOD will be the same as previous) > > Jamie > > On 2012-08-27, at 3:11 AM, epidata-list(a)lists.umanitoba.ca wrote: > > > I have a “.rec” Epidata data set with patients with chronic diseases > > (Diabetes and Hypertension).

Epidata analysis
by epidata-list＠lists.umanitoba.ca 27 Aug '12

27 Aug '12

I have a “.rec” Epidata data set with patients with chronic diseases (Diabetes and Hypertension). I would like to undertake some analysis to determine what is happening on the patients at different periods of follow up. (Month 3, 6, 12........) i.e. Glucose levels, BP, BMI....... Each period I select (M3, M6, M12...) I give an allowance of + &- 10 days. (e.g. for M3=90 days from the day of enrollment, I select between day 80 and day 100). This is because patients did not always respect their appointment dates. In the period selected (between day 80 -100) some patients for several reasons were seen more than once. I would like to select only one visit date in case of moth 3 follow up that is closest to the 90th day from date of enrollment .(e.g. a patient had a visit on the 80th day and 95th day, I want to select the 95th day visit which is closest to day 90)..... How do I do this with Epidata analysis? NB: My variables are “enrolment date” and “visit date” Kwal

100% converting rec to epx
by epidata-list＠lists.umanitoba.ca 27 Aug '12

27 Aug '12

Now it is clear that the converting (aka Import, "Add data structure...") of REC-files into the new epx-format doesn't work 100%tly. Plausibility checks are not importet. This is one of the BUGs I can see. Maybe there get more lost in the conversion. Is there a bug-tracking system where I can add and monitore it? Where can I see the development time table? I really need to update my project to the new format. Of course I need a complete converting routine for it. I won't do any work again that was done before in the old version.
