Dear Pierre-Yves:

Explicitly, you would have - example - a data set that you read and manipulate in EpiData Analysis [classic] as follows:

cls close read "original.rec"

* Contains variables VAR01, VAR02, .... , VAR19, VAR20 * Has 1200 records

* 1) Reduce number of variables * => keep only some variables to your choice: keep var01 var03 var05 var10 var11 var16 * if the converse gives less to write, use: * drop var02 var04 var06 var07 etc

* 2) Reduce number of records [assuming sorted by your preference] * Select only the first 500 records: select recnumber<501

* Save the new data set: savedata "reduced_set.rec" /replace

* Use the new set: cls close read "reduced_set.rec"

* All this is in the superb help file which you get with F1 in EpiData Analysis V2.2.3.187

Best regards,

Hans

Dear all,

I need to create a smallest datafile to work on it for logistic regression In EPIINFO6 it was very easy. the command was:

route c:\data\preclog.rec

write recfile chgt multi capot diaf foam withdraw cream depo rythm pil iud \

precl \

For epidata it is logopen "c:\data\preclog.rec"

but after, write recfile does nor work in Epidata

What is the process please?

Thanks
