Dear Tiago Castro,

  Why we need non-linear initial conditions here,and what is the growwth factor? Looking forward to your reply.

Best wishes,

Dear Zhengyang,

  The first 2 numbers stand for the redshift of IC and the growth factor at this redshift. The first two columns are the linear k and Pk. The second two are the non-linear k and Pk assuming Peacock & Dodds formula.

  I couldn't understand the data of "inputspec_snapshot.txt" of the example DM-L50-N128. What do these four columns of data mean,and what do the two numbers at the beginning of the data mean? Could someone tell me the solution.

  Thank you for your help!

Best wishes,

Zhengyang Zhang
