editing qes- and chk-files?

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)

corrupted files

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 Dr. med.

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! Dirk Nicole wrote: > I cannot open the EpiData rec files from my colleague, the error > message "one or more records are corrupted" shows up.

Re: Import XML EpiData files from R

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? Regards, Dr. Pedro Emmanuel A.

Import XML EpiData files from R
by epidata-list＠lists.umanitoba.ca 02 Aug '12

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? https://github.com/daudi/Epidata-XML-to-R kind regards, Dr. Pedro Emmanuel A.

Transpose from wide to long
by epidata-list＠lists.umanitoba.ca 02 Aug '12

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
