Here is an old EpiData project with seven sheets (rec-files). The doc about the project describe how to add "user-defined variables". Sheet number 7 is prepared for this and the user just have to edit the qes- and maybe the chk-file with an text-editor.
It sounds realy old and obsulet. Am I right?
Convertet the rec-files to the new epx-format there is no need to edit the file manualy with hand, right? There is the EpiData Manager for this job, right?
Can I forget the qes- and chk-files if I have the new epx or are they related to each other?
I'm quite new with EpiData but I'm working on an old project that use a EpiData version from 2005.
I need to know what happend to EpiData in the last 7 years. ;)
Am I right that in 2005 there where only one EpiData package.
But know it is splited into Manager, EntryClient, Analysis?
What is the big difference between 2005 and now?
This may be a stupid question,
I used the new version of Epidata to create a database and I want to create an entry (V3) the sum of the previous two entries (V1 + V2):
V1 = x
V2 = y
V3 = sum (V1 + V2)
Can someone give me the procedure or point me to a good tutorial?
thank you very much
= ps files are in format (. epx)
Both new but both very promising and well worth a try

Dear all
I cannot open the EpiData rec files from my colleague, the error message
"one or more records are corrupted" shows up. My colleague can open the
files normally. We are both using EpiData version 3.1.
I looked at the files in the notepad, but it seems to me that they look
like my own files (which are fine).
Can somebody help me? I need my colleague's files to validate duplicate
files with my files.
Thank you very much, best wishes,
Nicole

Nicole,
How do you exchange the .rec-files? Via a Unix operating system to
Windows, e.g. via the internet? It may happen that this modifies the
<cr><lf> (carriage return/line feeds) at the end of the lines.
One solution would be to send/receive files packed in .zip files, that
way the <cr><lf> characters should be kept as they are. Another
possibility is using a good text editor (like Ultra Edit) that allows to
modify the CR/LFs from Unix text file to Windows text files or vice
versa (i.e. to repair them).
Please let me know whether this was helpful!

Jamie,
Thank you for your effort. Sometimes I use Stata format as an intermediate
as Stata datasets contains all the data dictionary. However, for data
management within clinical research (such as checking for duplicates, NAs
fields, inconsistencies and so on) doing repetitive procedures manually is
not that effective.
Have you ever thought to share this development effort with the R core
team? The R guys which developed and maintain the foreign package?

EpiData friends,
One the things that was limiting me to definitely move from 3.1 to new
EpiData with new epx and epz format is that I was not able to import
epx/epz data form within R. Currently, from a R users list I was awere of
this user made function. So now Im will try to let 3.1 go and gradually
transform my files to XML based formta. If there is any R use in this list,
could any help me test if it works nicely?

Hello,
I have a parent file where all family members are represented as one
observation. Some of these families are relatively large. This makes it
impossible to print the information on one page. I did merge the parent
file with the child file. The drawback here is that not all family
members are present in the child file and we would like to include all
family members on the list.
To resolve this issue, I would like to create one observation per
family member. Is it possible to code this in EpiData Analysis?
For example:
Family Mom Dad
Child1 Child2 Child3 .....etc
1 2 1
A B C
To:
Family Mom Dad
Child
1 2 1
A
B
C
OR:
Family Mom Dad
Child
1 2 1
A
1 2 1
B
1 2 1
C
Thanks,
Renate
