Can I create an Column Error Map from text values in "Defect List" / Cosmetic Correction

TerryTerry
in PixInsight
Is it possible to take the text values saved in the "Use Defect List" within Cosmetic Correction to create an error map of columns?

Sorry for the long title, didn't know how to condense it.

    Hi Terry,

    Can you post your values?
    (Would it be possible to simply make it once using Pixel math? Once you have the image... you wouldn't need to do it again for a while).

    Hi Adam,

    I certainly can.  Below are the values saved from my aging STL :)    Yep there are a few cols with issues.

    Wait...these are not columns... aren't these just single pixels?
    How in the world did you make this list initially??
    The easiest way I know is to write a tiny Python script/code that inputs the text file and outputs
    putpixel statements in Pixel Math. This would work perfectly. If you don't write a program to do this for you... you will need to type:

    pixel(0,1534,3027);
    pixel(0,262,3975);
    pixel(0,218,3959);
    ...

    This assumes you are starting with a white image. (The defects in a defect image are black).

    Hi Adam.  I was
    following cosmetic correction video to try and create a “funky column map”.  I used cosmetic correction, Use Defect List
    with a BIAS frame.  I went the top of
    each col, BUT, I forgot to tick the “Limit” box.  From here I saved to a text file

    I changed the last value to the value at bottom of the chip “2671”.  I think that is correct now, sorry about that.  

    Terry (still using training wheels)
