[ncl-install] After install to cygwin, no response to any command

[Robert Cohen]

I replaced my 64-bit Cygwin with the 32-bit Cygwin and now everything runs fine.  Thank you for that.

As for my 4-GB RAM problem, I did a small test so far and it seems that I am running up against the 4-GB limit although it is higher than the limit I had on a 32-bit machine (since on the 32-bit machine only a portion of the 4GB was available).  I will know later today if I can go beyond 4 GB.

My plan is to generate a file that is about 2 GB, containing 8,760 frames (1 frame per hour over the course of a year).  I would then create a movie loop of the output.

If there is another way to get the movie loop without going through idt or a problem that does not have 4GB limit, I can certainly do that instead.

Hi Robert,

I honestly don't know the answer to your question. I've never tried to use idt for really large files. idt is a rather old program that we don't update much any more.

The "64-bit" nature in the case of something like idt should not affect how much memory it is allowed to grab, but it might affect whether you can open a file larger than 2 GB at any one time.

How big is the file you need to generate, and how many frames does it have?
