Hello!
I have database made of two parts. When we finish data entry in "part 2",
instead of moving to new record file, and we expect to see part 1, we get
new record file in part 2.
Example: when we enter questionnaire number 1-part 1. Then part 2 opens for
the same questionnaire 1. At the end of part 2, instead of moving to
questionnaire 2 to start doing data entry, it gives us new record file under
part 2 for questionnaire 1.
Any advice(s)?
Thank you in advance!
Best regards!

I have a problem with results of calculation during double entry. During
> double entry, all calculations give same results as first entry except only
> for few subjects.
Mystery sometimes happen - I am not sure what the problem is here.
But we are just now working on different aspects of double entry
verification. With the next build of EpiData Entry these errors should
be fixed. For the finding of errors it would be very good if users
could supply us with the rec+chk files giving problems. If someone as
indicated on the list recently have examples creating problems please
provide them for us for testing. The known issues to settle are:
1. Sometimes the double entry verification does not move on to the next
record (problem with range definition in last field)
2. The calculation error indicated today.
Send the files as zipped files (e.g. with few records, say 2-5) to info
@ epidata.dk with a clear subject indicating that this is not spam, e.g
EpiData test case for finding double entry problem.
2.
Exporting to SPSS from old to new version of EpiData. The EpiData file
format has not changed apart from the addition of encrypted fields and
<yyyy/mm/dd> fields
What most likely cause your problems is that the setting of "variable
name" as first word or automatic was different on the two computers.
Also for export to SPSS you do not need the QES file, but the chk file
(definition of value labels and missing data) + the rec file (definition
of fields, variable labels and all of the data).

Hi,
I have a problem with results of calculation during double entry. During
double entry, all calculations give same results as first entry except only
for few subjects. I checked my formulae with other software and they look
OK. This bug is not systematic thats why I have difficulties finding
errors. I dont understand why this bug appears only for few subjects. They
have not the same characteristics.
Who can tell me what king of error it could be, because I dont know anymore
what to looking for?
Below, calculations :
pspef
AFTER ENTRY
IF (sex = 1) and (height < 162.6) THEN
pspdpef=(height * 0.073) - 5.98
ENDIF
IF (sex = 1) and (height > 162.5) THEN
pspdpef=(height * 0.125) - 13.14
ENDIF
IF (sex = 0) and (height < 152.6) THEN
pspdpef=(height * 0.079) - 6.79
ENDIF
IF (sex = 0) and (height > 152.5) THEN
pspdpef=(height * 0.064) - 3.94
ENDIF
IF (sex = 1) THEN
pssdcpef=(pspef - pspdpef) / (pspdpef * 0.18)
ENDIF
IF (sex = 0) THEN
pssdcpef=(pspef - pspdpef) / (pspdpef * 0.2)
ENDIF
psppef=(pspef/pspdpef)*100
END
END
pspdpef
NOENTER
END
pssdcpef
NOENTER
END
psppef
NOENTER
END
Example : sex = 1 , height = 132.8, pspef = 4.90
First entry (good results)
pspdpef = 3.71
pssdcpef = 1.78
psppef = 132.1
Double entry
pspdpef = 3.71
pssdcpef = -1.15
psppef = 79.2
Thank you in advance for your help.

Now there are in the qes.file many, many @ signs and they also appear when we export our data into SPSS (in the variable labels). If we skip the signs, in some cases variable labels in SPSS don´t exist anymore.

Hello!
I sent last year information about an introductory guideline about EpiData.
I wonder if anyone has used it?
It used to be under EpiData page for a while, and now it is under my
university link:
http://onkpat.ki.se/1?node=47234
In case you have used it, can you please write me back your feedback about
it? I am intending to develop further versions of how to use EpiData, and
need feedback to support my case for funds.
Best regards!

Another form of solving a corrupted file is to use statransfer(a statistical
software that enhance file transfer from one format to other eg. from spss
file to rec or any other file)with this software you transfer the file back
to rec and it will solve your problem.

In some versions of some computers open files can get "messed" up if power is suddenly lost.
Over the years we have strengthened EpiData Entry with several alternative mechanisms to try to avoid problems in this situation (e.g. only one record at a time is in memory. The rest is on the harddisk or floppy.). But despite this the error have been reported at rare instances. Also over the years I have seen files from this situation which was a combination of a rec datafile, a word document and a presentation or drawing. In other words this is part of a operating system problem.
How to resolve ?
If a corrupted file message is given you can do the following:
Manual repair of corrupt files:
1 Make a second copy of your REC and CHK files and do the following
(MAKE SURE IT IS A COPY !!!):
2. Verify that YOU HAVE THE ORIGINAL CORRUPTED file in a separate place.
3 Open the extra copy of the REC file in any ascii editor (e.g. notepad.exe).
4 Make sure you are using a fixed font.
5 Look for records with strange or odd formatted records and delete the complete record
(Make a note of which one such that you can re-enter it later in EpiData)
6 Delete the parts with a strange format.
7 Pay particular notion to length of lines. All records should show same pattern.
8 Save the file and try to open in EpiData.
If you think the above is hopeless - then try to regain other documents or files that were also open at the time, e.g a spreadsheet, a text document or a database from another programme than EpiData.
The above is a modifed version of a user supplied explanation earlier.

Hi, I´am a new user, I need some help, and my english is a bit poor. Anyone can help me in spanish ?
Thanks in advance,

A good recovery strategy when something goes wrong is:
1. Ask yourself "When was I in control the last time"
2. What did I do since I was in control of the situation.
3. What might I have done wrong since the control.
4. What was I intending to do at the time when I felt no longer in
control of the situation.
5. Do I think the "loss of control" is due to a software error, a
hardware (e.g. harddisk broken) error or a user error ?
6. How much work should I repeat to continue working from my last backup
of all data (I assume you do have a copy somewhere).
7. Can I repeat the steps from the "in control situation" to the "out of
control situation" and the same thing happens every time.
If you can answer these questions you have a very good clue for the
solution or the appropriate information to tell someone who can assist
you - e.g. other users on this list.
