Star Alignment Bug?

     Thanks. I got excited because that seemed to be the answer, except it only allows entry of one directory.  In combining old and new data from different cameras (that I expect to be doing a lot which is why I need to keep persisting to make this work), the c_cc.xisf files and  .xdrz files are scattered over 4 different directories on 2 different disk drives.  This would be a drag to have to copy them all into one directory some place just to make Drizzle Integration work.
     Like many other programs, PI should just give you a Browse option any time that it can't find files so you can fill in where to find those particular files until it can't find some other files, etc.

Just use a text editor and change the file paths in the .xdrz files to match where the files are now.

Cheers,
Rick.

Great idea.  I didn't realize they were just text files.  Thanks.

Rick-
    That worked great on my laptop with Replace-All in Wordpad done on each of the 52 Lum .xdrz files! DrizzleIntegration happily ran.  A little tedius and now onto the R,G,B and Ha files but it did save the situation.   

    With my new desktop computer and different disk drives, I'm going to face this again every time that I try to process a new image and want to combine it with old data that I have on the same image.  Since I'm sure I'm not the only person with disk crashes or who wants to occasionally combine with old recovered data, I still think it would be better if PixInsight offered a Browse option every time it can't find a file its looking for so the user could enter the new location just once (until the next unfound file).

Thanks all.

Here is the a way that I have gotten around this problem with many programs over the years both at home and on jobs. First I never keep data on the C: drive in windows. I always use a different physical drive. If I have to share the data on different computers I make sure that the directory structure is the same. That is lets say "drive":\data\moon\01_12_2005 as an example. The drive letter is the problem here. Well Windows allows you to change the assigned drive letter. You wouldn't want to do this with the system drive but data drives are not as much of a problem.

So when I want to work with PI on one machine here at the house and I have my data on a external USB 3.0 drive, that drive has the same drive letter now on both machines, 'M". I choose M because I know that letter is way down the list and will most likely be available on most systems I would use that drive on. So all of my saved projects or in this case drizzle locations are the same on both machines. If I get a new machine it's simply change the drive letter in the new machine.


I'm not saying that a browse function wouldn't be good but this is how I've dealt with this problem since the DOS days.

Thanks, Mike-
I did have all my astro image  files on a second internal J: drive that survived the computer crash.  But shifting to my laptop and backup drive, I couldn't maintain the same structure if I had wanted to, I don't believe.  My new computer will have a similar second drive which I also will name J:,  where I will continue to keep all my astro image data on a separate drive.  I should be back to the original directory locations for both new (ML16200) and old (ML8300) files.  So I think in the future, once this is setup, I'll only have to change the Star Alignment /Star Matching option  from the default "pentagons" to "triangle similarity" in order to handle the mirror problem and process them together without further problems.  Yeah.
