Do you mean: some initial rows of text?
Then you may rather use csvRead(): 
https://help.scilab.org/docs/6.0.0/en_US/csvRead.html
and its last input argument "header"


> Koeffizienten_DM=file("open",  "C:\Users\f.nikolaisen\Documents\Bachelorarbeit\Simulation\Koeffizienten_DM_Matrix.txt",  "old")

Koeffizienten_Pfad  =  uigetfile(["*.txt"],'',"Wählen Sie die Datei Koeffizienten");

Koeffizienten_DM= file("open",Koeffizienten_Pfad,  "old");

Koeffizienten_DM= file("open","Koeffizienten_DM_Matrix.txt",  "old");

The multiple sections about files are likely the worst.
