WBPP Not Grouping the way I want

I have data from three separate nights.  I have organized the Flats and the Lights into separate folders for each night.  Each folder follows the OBJECT_DATE convention outlined in the Fundamentals video.  For example:  NGC6992_20230711.

I add the Keyword "NGC6992", and ensure that "Pre" is checked.

When I add the directory to WBPP, the Flat files are grouped the way I expect; that is, there is a separate "Group" for each night in the "Flats" tab.  Furthermore, in the "Calibration" tab, each of the three dates is displayed in the new "NGC6992" column.

However, in the Lights tab, there is only one group and it is by the Exposure.  Additionally, in the "Calibration" tab, there is only one line, and under the new "NGC6992" column, the value is "300" (which is the exposure).

I have tried putting both the Light and Flat files in the same subdirectory (

Example:  C:\Users\.......\Lights\NGC6992_20230711\**All Lights and Flats for that night**
\Lights\NGC6992_20230719\**All Lights and Flats for that night**
\Lights\NGC6992_20230723\**All Lights and Flats for that night**
)
 ...as well as separating them into to separate directories (

Example:  C:\Users\.......\Lights\NGC6992_20230711\**All Lights for that night**
\Lights\NGC6992_20230719\**All Lights for that night**
\Lights\NGC6992_20230723\**All Lights for that night**
\Flats\NGC6992_20230711\**All Flats for that night**
\Flats\NGC6992_20230719\**All Flats for that night**
\Flats\NGC6992_20230723\**All Flats for that night**

)

Both directory structures had the same result.
Is this the expected behavior?

I have included screenshots to further illustrate.

    UPDATE**

    It seems that the Folders above as well as the individual image file names are factored in the grouping?

    "NGC6992" is part of the image filename (i.e., "Light_NGC6992_300.0s_Bin1_20230711-230003_0001.fit")

    When I changed the subdirectories to be "\VAIL_20230711", etc... It grouped the Flats and Lights correctly.  However, it could no longer match the Bias and Darks because "VAIL" is part of the file path name a couple folders above.

    I understand this point, but I guess I didn't realize that the image file names were also considered in grouping.  My takeaway is that your Folder Name/Grouping Keyword cannot exist anywhere in the directory path or file names.

    So, I used "NIGHT" for the folder names/Group Keyword.  And now everything lines up.

    I think this is what you explained at 3:52 of the "WBPP: Grouping for Multi Nights Demo" video.  In my over-thinking it, I came away with the idea that the filenames don't matter, only the Folder names.

    Perhaps using Muppets names is the best course of action afterall....
  • YES. The full path is scanned (which included folders and things in the file name.. it is one long string that is scanned. You cannot have a keyword appear twice in the string. It must be unique. 

    Yes, you should really listen to me- muppet naming is a good idea. lol

    Good job on working through this. I suspect this exercise will strengthen your understanding of this.
