Help with "Iris" gradient removal & PixInsight

[Lester]

Hi all,

I have been trying to do gradient removal on my images without much luck. Scott uses Iris and gets good results for removing gradient in images. I have tried downloading Iris twice, and still get the same result. I can process images, but cannot do a gradient removal.

I load a image into Iris.
click on processing
click on "remove gradient (polynomial fit)
get message in box= Cannot save File
Nothing happens to the image.

With my frustration I have also tried PixInsight, got a username and password, downloaded the program, but cannot open it.

So very likely it is Me and my lack of computer skills.

Thanks for your help.:thumbsup:

I'm in the same boat as you Lester. I can't get IRIS to save my files either. Hoping someone can come to our rescue.

You have to set a path for your files in the Settings section, first.

For gradients, run "setsubsky 5", and then "subsky" in the command line window.

Hi Humayun, I must be thick as a brick (it is 4 a.m.) but that is no excuse for me. I can process using other settings within Iris and save. I don't understand why I would have to set a path, or know how to set a path. Also cannot find set subsky 5.

Thanks.

I've got this problem and I've just found out a solution for it with Windows 7.

I'm constantly getting "cannot save file", firstly I thought that running in compatibility mode might help - but decided to "run as administrator" first.

This solves the problem completely.
