This problem only occur when sample analyses do not tune.
The default methods loaded when upgrading to version 6.2, using the smart mode are automatically loaded in the methods list. The 2D C-H related analyses (HSQC, HMQC and HMBC) seemed stopped to work. However I re analysed using alternative methods from the library and it seems to work.
Solution: The autogain is set to false (which is fine), but the receiver gain is set to 0 instead of 50, so the signal is not amplified.
In the standard_smart.jdf, found the variable autogain which is FALSE. Changed the HMQC, HSQC and HMBC to
EXPOSE PASSIVE VAR autogain : BOOLEAN = TRUE,
Default autogain or rgain=50 now.
