Year with two digits
by epidata-list＠lists.umanitoba.ca 27 Apr '10

27 Apr '10

Hello Epidata Friends, I know this will sound repetitive and passed over but Im not finding a workaround. I have a very ancient rec file created by EPI6, this dataset was abandoned in 1999. My intention was to update the rec and chk file for new data to come in and update the up to 2009. I was trying to export using epidata entry tool to Stata and do several editing within Stata and then import it again from Stata to epidata to keep on feeding the dataset. My problem is that the dates of birth and follow-up start are configured as dd/mm/yy , that is Year with tow digits. When I open the data from within Stata, weird dates come. Just the years look weird such as 01apr2020. All the years are 2020 or 2019 and I know the yars may range from 1986 to 1999. It seems that is not only a problem to add the 19.. before the dates year so far. So I guess, since Epidata does not accept dates with tow year digits, it is exporting with error. Therefore Im accepting any suggestions to workaround. kind regards, Abraço forte e que a força esteja com você, Dr. Pedro Emmanuel A.

EpiData Entry and multiple simultaneous users
by epidata-list＠lists.umanitoba.ca 26 Apr '10

Hi there, I have multiple data entry clerks entering data on different Epidata REC files. Because of data entry back-log I wish to get additional staff to enter data on the said REC files simultaneously. I have overcome this problem by "splitting" (more like copying the file REC to another terminal) the database REC file (with its CHK and QES) so that 2 staff could enter the data at same time. The problem is that when we assign a unique studyid, in say RECfile#1, RECfile#2 can't counter check if that studyid is being duplicated. Could someone show me how to share a common REC file for simultaneous data entry? I know Epidata can't be run through a network server, or linked to a server database, like MS SQL sever, or MySQL databases. If it can could you show me how to do this? or even place the REC files on the network drive and share them for data entry, is this possible? How?

Hi Claire, At each time you finish entering a record, you will be asked "do you want the record on disk?" When you click or press return key the record is saved. Step 1: please go to File then > Close the form Step 2 : go to " 5.Document" then > View to view your data entered. Step 3: go to "6. Export Data" chose from the drop menu Excel then follow on screen guide. Step 4: your file will be exported to Excel where your original rec.file is located. Please let me know if I misunderstood your request and hoping this will help.

Saving Data...

Good Day, I have been searching the archived emails and help offerings to try to solve this problem and I have not been able to find the help I am looking for. I am presently running EpiData 3.1 with Windows Vista. I have created a questionnaire and loaded the values for the questionnaire. I clicked on the "Enter Data" button. I entered my data. Now, the only menu buttons I have at the top of the screen are the following: "FILE", "GOTO", "FILTER", "WINDOW", "HELP". Nowhere in any of these drop-down menus is the option to either save the data I have entered, or to export it (preferably to Excel) so that it can be saved there. Please advise. Thank you!

Data missing after merge - any ideas?
by epidata-list＠lists.umanitoba.ca 09 Apr '10

09 Apr '10

Hello everyone, I have two files - one fairly large (9000 records, 51 fields) and a second one with 500 records, and the same 51 fields. I can read and manipulate both files in Epidata Analysis but when I try to merge them using the common field of ID number, the second one has all missing variables, except the common field of ID number. I can't think what I'm doing wrong. Any guidance would be very helpful! Thanks, Susie Foster
