HVSR usage - please help No.2

[TerraAu]

I used a 24-chanel seismograph for 3C low frequency data. Unfortunately, the parameter setting was wrong (I did not specify to record only 3 channels), and I recorded 21 blank traces as well as 3 valid channels. By defining the components, I thought HVSR would work, but it did not, and the error message said it found less than 3 components (screen shot attached)

Could I make this work?

Select the 3 rows containing true signals and drag them to a new graphic (icon in the toolbar).
A new graphic with the only the 3 good signals will be displayed. Run the H/V tool, you should not get any error message.

Best regards,
