Hi Kamarul,
In ANSWERS on GRASS, name of a rainfall event and rainfall data file name
are different. When you are creating a new rainfall event, the program
requires that you have to specify a new event name. The rainfall datafile
created by the user can be stored anywhere, and can be used for as many
events as you want. The rain data _storage_ files created by r.answers,
on the other hand, have the same name as the rainfall _event_ name, and
are stored by the program in <MAPSET>/answers/data/<PROJECT_NAME>/rain
directory. Every event name must be _unique_, but you can use the same
event more than once.
If you want to use the same rainfall event again, you may do the following:
Do you wish to use data from a previously entered event?(y/n) [y]
Currently used rainfall event: rtest
Enter the name of the rainfall event:
Enter 'list' for a list of existing rain data storage files
Hit RETURN to cancel request
rtest *** enter any existing event name ***

If, on the other hand, you want to create a new rainfall event, use a new
name and specify the <PATH/raindata_file_name>. You can delete the
existing events by going to <MAPSET>/answers/data/<PROJECT_NAME>/rain,
and deleting the rain data storage files.
Hope this will help.
