Hi @geoyayaispoor,

You have to increase the maximum memory settings, to do so, you can change it like this:

1. Open the “Options” dialog by clicking on the menu “Tools/Options”
2. Switch to the “Performance” tab
3. Edit the “VM Parameters” clicking on the “…” button

You should see something like this:

-Xmx5120m
-Xms256m
-XX:+AggressiveOpts
-Xverify:none
-Dnetbeans.mainclass=org.esa.snap.main.Main
-Dsun.java2d.noddraw=true
-Dsun.awt.nopixfmt=true
-Dsun.java2d.dpiaware=false

The -Xmx5120m is the maximum memory (5GB in this case) change it to a bigger value (e.g. -Xmx8192m), save the changes and re-open SNAP.

It should work now.

Best regards,
Martino

NOTE: put a reasonable maximum amount of memory depending on your computer configuration!
