mathalign with \{ ?

mathalign with \{ ?

[Xan]

Hi,

I have

\placeformula[-]
\startformula
  F(n) = \startdisplaycases
    \NC F(0) + 2 \ln n!!  - \frac{n}{2} \ln 2  \MC \text{si } n \text{ 
parell} \NR
    \NC F(1) + 2 \ln n!! - \frac{n+1}{2} \ln 2 \MC \text{si } n \text{ 
senar} \NR
  \stopdisplaycases
\stopformula

and I want to put

\placeformula[-]
\{
\startformula
  F(n) = \startdisplaycases
    \NC F(0) + 2 \ln n!!  - \frac{n}{2} \ln 2  \MC \text{si } n \text{ 
parell} \NR
    \NC F(1) + 2 \ln n!! - \frac{n+1}{2} \ln 2 \MC \text{si } n \text{ 
senar} \NR
  \stopdisplaycases
\stopformula

But I received error.
I have MKII.

How can I put braces and do that enumeration formula is at middle 
possition (not in first or last line, just in the middle). I use Aditya 
manual but I did not see it.

Xan.

Can you visually show what you want to achieve?

Yes. I attached a hand free picture.
I hope this serves you.

Thanks,
