A vaccine; an alternative method

I previously posted a technique to separate delta waves from preceding waveforms so that delta waves associated with background rhythms are not over-interpreted. A vaccine against overcalling

Sometimes this technique does not work, simply because as the screen advances by a fixed 1 second at a time on my Nihon Kohden software. For general purposes I always have my "snipping tool" open on my taskbar, as I use this multiple times per day. It is very useful for snipping (in other words copying) your screen to your precise specifications. Hence, if you are concerned that a focal or generalised delta wave is preceded by a wave or a sequence of waves that may or may not represent a spike and wave discharge, open "snipping tool" and snip the page of the EEG up to but excluding the delta wave. You will obtain an image of the page of the EEG that includes all the waves up until the moment that the delta wave starts and you will be able to determine if the last wave on the right-hand side of the new, snipped page is sufficiently distinct from the preceding background rhythms to consider it a spike.

If you have never heard of the "snipping tool", I think it comes bundled with your Windows software and you can simply click on the search bar on the bottom left of your screen and type in snipping tool. It is one of my favourite pieces of software. You can right click within your browser and click on screenshot, but it does not work with my EEG software.

Here is an example. Let us say that I wanted to exclude the artefact on the right side of the image but include the page of the EEG that includes the eye movement that immediately precedes the artefact in the following image:

So, you haul out your snipping tool and drag it from left to right and snip the image precisely to suit your specifications. You can then look at it in the snipping tool and if you want to save it, you can simply click the "save as" in the top left of the software (it saves it as a JPEG). It will then look as follows:

You get the picture?
