Load Images, deltavision

Hi all,

I’m trying to correctly load and group images from a deltavision DV file. I’ve attached the pipeline I’ve been using although I’m not sure it will be much help without the images file (which is 2.7 GB).

The DV file represents a single well of a 96-well plate where I’ve imaged 16 fields per well taking 20 z slices for 4 channels.

Really, I’m just playing around right now, but as a test, the pipeline I have just makes a maximum intensity projection of the DNA images and saves the file.

When I run the pipeline, I’m getting the following error:

Traceback (most recent call last):
File “/Applications/CellProfiler.app/Contents/Resources/lib/python2.7/cellprofiler/pipeline.py”, line 2094, in prepare_run

ValueError: Zero-length selections are not allowed

I’ve attached the pipeline I’m using and screen shots to show how I’ve grouped the images. I’ve loaded the images based on the header metadata and first defined images by ‘C’, then made image sets by ‘Series’ and ‘Z’. Here, there series represents each field. Last I grouped the images by Series.

Any thoughts?

HI all,

A small update. I was actually patient enough to let the pipeline run and it looks as though it’s generating the proper images despite the error when starting the pipeline.


Any chance you might be able to upload a smaller version of the image file, so we can take a look to see if it’s a bug we can fix?

I am actually experiencing the exact same problem. As was posted above, if I let it run, everything seems to be fine. Was there ever any update on why this happens/ how I can prevent it in the future?

Hi @ kMichaels,

To my knowledge, we don’t have a DV file here to test. Can you upload one here, or link it in, say, Dropbox?
