Hi,

This is my original design with 20 blocks with 10 choice sets in each block. Now we would like to reduce the number of choice sets in each block such as only five. Then we will need 40 blocks instead of 20. Can I just use eval command to achieve this? Will eval command generate the new choice sets with 40 blocks just as what mention in Ngene manual page 178? Or it just evaluate the new design? Thanks for your help.

Regards

Lily
