cwViewer

cwViewer is a tool for the easy opening, analysis, manipulation and plotting of cw EPR data and superceeds the previous function cwPlotter

With an intuitive user interface, users can quickly create professional looking figures in seconds and export them however they like. Here’s a quick demo introducing the basic features:

cwPlotter comes as part of the EPRtoolbox or as a direct download

Users can quickly load

  • a single file
  • a folder of files
  • a single file with a third dimension (such as power) (*.YGF file)

Manipulate the data using

  • an auto-zeroing function
  • a normalization function
  • a Savitzky-Golay smoothing function
  • a digital smoothing function, using a moving average
  • a smoothing fast Fourier transformation

View the spectra

  • with an automatic or manually selected range
  • as a single spectrum (with slider to move between them)
  • overlaid on top of each other
  • staggered (on x, y or x and y axes)
  • plotted against Magnetic Field or g-value

From the menu, the figure can then be exported or saved in a variety of common image formats

EasySpin Integration

As of v12.7 cwViewer offers limited EasySpin integration. From the window menu select EasySpin fitting

This loads the EasySpin fitting window to the bottom-right of the main cwViewer window

From here you have several EasySpin parameters that you can play with. The EasySpin Fitting window loads with pre-defined parameters for nitroxide spin labels.

When happy with the options click the Fit button and whichever spectra is currently on screen will be fitting in a new window in the usual way for EasySpin.

Faced with fitting well over 30 experiments at room and low temperature at multiple frequencies, as all of my experiments are spin-labelled mutants of the same protein then surely their EPR properties would be similar. I decided that there must be a …

Savitzky-Golay - sgol

The Savitzky-Golay smoothing function essentially applies a local polynominal fitting routine to a series of data points to then find the smoothed data points. This has the benefit that for sharp intense peaks (common to EPR) that the line broadening …

Frequently asked questions

What distinguishes you from other developers?

I've built data pipelines across 3 continents at petabyte scales, for over 15 years. But the data doesn't matter if we don't solve the human problems first - an AI solution that nobody uses is worthless.

Are the robots going to kill us all?

Not any time soon. At least not in the way that you've got imagined thanks to the Terminator movies. Sure somebody with a DARPA grant is always going to strap a knife/gun/flamethrower on the side of a robot - but just like in Dr.Who - right now, that robot will struggle to even get out of the room, let alone up some stairs.

But AI is going to steal my job, right?

A year ago, the whole world was convinced that AI was going to steal their job. Now, the reality is that most people are thinking 'I wish this POC at work would go a bit faster to scan these PDFs'.

When am I going to get my self-driving car?

Humans are complicated. If we invented driving today - there's NO WAY IN HELL we'd let humans do it. They get distracted. They text their friends. They drink. They make mistakes. But the reality is, all of our streets, cities (and even legal systems) have been built around these limitations. It would be surprisingly easy to build self-driving cars if there were no humans on the road. But today no one wants to take liability. If a self-driving company kills someone, who's responsible? The manufacturer? The insurance company? The software developer?
