Noise input form file for vsource

Hello

I had two questions:

1) Can I enter formula (e.g. one as below) in the noisefile that I want to be included for defining the noise source. I am asking this becuase when I tried it, I got errors but when I entered the same thing in via Noise/Frequency points in the vsource Object properties, it ran fine. But it has limitation of 10 pairs only. Does the file input also has some such number-of-pairs limitation?

fpfd*0.05 propsdnoise_multfac*((2*sin(pi*0.05))**(2*modord-2))

fpfd*(10**(log10(0.05)+0.1)) propsdnoise_multfac*((2*sin(pi*(10**(log10(0.05)+0.1))))**(2*modord-2))

fpfd*(10**(log10(0.05)+0.2)) propsdnoise_multfac*((2*sin(pi*(10**(log10(0.05)+0.2))))**(2*modord-2))

fpfd*(10**(log10(0.05)+0.3)) propsdnoise_multfac*((2*sin(pi*(10**(log10(0.05)+0.3))))**(2*modord-2))

 2) As you can see in the example above, I am trying to do the logarithmic interpolation. Is it possible to do that automatically as this interpolation is still not good enough as what is happening is I calculate logarithmic interpolated value by the equation aobve but the points between them are interpolated linearly inside the simulator. Is there any solution to it?

Thanks.
