Hello Andreas,

Code: [Select]

chunk = PhotoScan.app.document.chunk
step = PhotoScan.app.getInt("Specify the selection step:" ,5)
index = 1
for camera in chunk.cameras:
      if not (index % step):
            camera.selected = True
      else:
            camera.selected = False
      index += 1

Hi Alexey,

Great script!
I need the same script but to select the images which have more than 4 ot 5 overlap images.

Thank you

Hi Alexey,

I'm wondering how I might modify the script above to select photos that are contained in a text list.  I've seen some other reference examples on the forum to opening a text file but I'm not quite getting the code correct.  Would like to do something like reading the text file containing a list of the photo labels that should not be selected (inverse selection from the list) to get anything not in the list (run_list1.txt) selected.

chunk = PhotoScan.app.document.chunk
sourcepath = "/Volumes/G-Tech/run_list1.txt"
file = open(sourcepath)
photoslist = file.readlines()
file.close()
photoslist = [photo.split()[0] for photo in photoslist]
for camera in chunk.cameras:
      if not (photoslist):
            camera.selected = True
      else:
            camera.selected = False

Thanks for any suggestions.

Ok.  Solved this code issue with the following...debugging print lines are commented out.

Code: [Select]

chunk = PhotoScan.app.document.chunk
sourcepath = "/Volumes/G-Tech/run_list1.txt"
file = open(sourcepath, "rt")
photoslist = " ".join(file.readlines()).split()
file.close()
#print (photoslist[0])
#print ("\n")
#print (chunk.cameras[0].label.split("'")[0])
for camera in chunk.cameras:
      if not (camera.label.split("'")[0] in photoslist):
            camera.selected = True
      else:
            camera.selected = False

Hello Robert,

I think that for the condition inside the loop you need to use something like:

Code: [Select]

if camera.label in photoslist:
For the debugging purposes you can also print the photoslist contents to the Console to be sure, that it is read properly.

Hi Alexey,

Just tried that out and the code worked great...much more streamlined.  Appreciate the suggestion.

Thank you.
