Troubleshooting

titleDeconvolution processing not giving expected results..

This usually happens when the image files do not contain the correct metadata.

  • Make sure to save the files with all available metadata on the microscope used for the acquisition.
    This usually requires to save the files in the software proprietary format (.nd for NIS-Elements and Metamorph, .czi for Zen,...)
  • You can always add the correct calibration values after acquisition (pixel size in XY and Z, wavelength, Z-step)


FAQ

titleCan I use this workstation remotely?

Yes and No. You can't start the software remotely but you can start the software locally and then connect remotely to make sure all is running smoothly. To do so you need to request permission to the platform manager.

titleWhich deconvolution method should I use?

There is no single answer

  • If you have a single plan you should choose 2D-deconvolution
  • If you have a Z-stack you should pick 3D-deconvolution.
  • If you want to have a quick view of the result you should use Fast Deconvolution.

Quality wise, the best results are achieved using blind and Landweber. However these methods required a long processing time (several hours for big files)

For more information about deconvolution method refer to paragraph 1.2.2 Choosing the deconvolution Method of the NIS Offline Deconvolution Manual (pdf)
