Wavelet Motion Correction error

Hi all,

        I have been experimenting using various motion corrections for my data and when trying to use the wavelet motion correction a message pops up saying the function cannot be ran. See image. The error message says to include the Intensity_to_Delta_OD function as it is a prerequisite for the wavelet function, but I already have that as part of the processing pipeline as you can see in the image. This error persisted even if I clicked 'Continue anyway' and when running the processing stream simply did not apply any wavelet correction. It also persisted if I re-added the intensity to OD function to the pipeline or restarted Matlab or Homer3.

I am using Matlab 2021a on a windows PC with the newest version of Homer3. No other motion corrections resulted in any issues.

 

Thanks in advance for any advice.

-Nathan

Hi Nathan,

The prerequisite error is being raised by mistake-- I will look into fixing this.

By pressing Continue, though, you are allowing the function to run. If it is not applying any correction, you are using the incorrect parameters.

@sstucker Thanks Stephen, I'll have another look at the parameters I was using. Cheers! 🙂

Hi Nathan and Stephen, 

I am running into a similar problem with the wavelet correction. It lets me run the analysis but then it freezes and the error message “DWT Extension Mode: Periodization” keeps coming in my command window (top image). I have to forcefully cancel in order to exit from it. 

I checked the parameters and I am using the default parameters (bottom image). I tried to run it after changing the iqr value too but it kept giving the same error as above.

I am running MATLAB 2020b on Mac with Homer3. I have tried different motion correct options on the same file(different copies) and haven’t run into any problems.

Nathan- were you able to remedy this?
