First led position

Questions
1

Hi guys,

Due to a limitation on my wall, I could not setup my first led at the corner of my setup so I have put my first led somewhere in the middle of my TOP LED segment as start point. Could someone please point me to the right direction where I could move the first LED position to the middle of the top segment?

Example:
1>2>3>4>5
13-|-|-|-|-|-|-|-6
12-|-|-|-|-|-|-|-7
11<10<9<8

My first LED position would be LED No. 3 in this case.

Many thanks,

Long

You want to check out the use of the ledmap file.: LED mapping
It lets you create a virtual map to renumber the physical LEDs in the order you want.
