GC retention index

Hello everyone,

I am working with GC and use Alkane standards to get retention indices.  In the MS-DIAL tutorial it is explained, how the retention indices are calculated. However, I can't find info on how extrapolation is done. For example, my Alkane index file is starting from C8 but MS-DIAL is then also calculating retention indices for compounds with lower retention time.
I hope someone can explain to me how this is calculated.

Thank you!
Bernadette
