Thanks a lot.
3) Do you anyway suggest to use the -H parameter or not?
4) When I open the .ti3 file with the command
chartread –v -H –T0.5 –B E4880
(I tried to use -T0.5 to improve number or reads per patch, just to see what
happens)
I get this result (for each patch, this is the first one):

Now the question is:
What are this spec_XXX about?
