REW Beta Release java.lang.NullPointerException in Alignment tool

[leov]

I'm playing around with the Alignment tool. I get the following error when I click, for example, Align phase slopes at cursor. I also tried it with the 32-bit version and both do the same thing.

REW V5.20 running JRE 1.8.0_202 64-bit on Windows 10, en, US, windows-1252 at 96 DPI

Your measurements are the results of magnitude averages that don't have any phase data, so there is no phase to use. I'll make a change to disable the feature in those cases, but the tool is for use with measurements that have phase responses, without them there is no meaning to the idea of time alignment.

Yes, thank you. I deduced that after some trial and error. I did not realize the phase responses were not there. Preventing it from being used would be a good fix. Thanks again.
