Dear Tomas,

Yes I've adapted the Heap Size (tried it with 2, 3, and 4 GB) on Win7
64bit. I've only got 4GB.
I've got Orbitrap data:
original Raw files: ca. 250mb
mzXML converted with MassMatrix file converter --> centroided ca. 550mb
(I've initially used the centroided mzXML files, but Mass Detection gave
error message, therefore I switched to profile data.)

mzXML converted with MassMatrix file converter ca. 550mb
mzXML converted with Proteowizard file converter ca. 300mb

I've tried all of them. Always same result.

Thank you for your support!!

Best regards,
David
