- "| | | \n",
+ "This is applied to integrating coordinate systems across analytical instrumentation, with each instrument typically having its own individual coordinate systems based on imagery and/or a sample stage. autopew also includes functions for importing and exporting files, for automated generation of point sets within a relevant format for each piece of analytical instrumentation. For example, `autopew` outputs currently included a `.scancsv` file which can be directly imported into Chromium laser ablation navigation software.\n",

+ "### Why use autopew?\n",
+ "\n",
+ "`autopew` is designed for easy referencing between analytical equipment and/or images. This allows the time spend on analytical equipment to be more effectively used for data collection rather than spending valuable time locating the areas of interest (at least where this functionality doesn't already exist). Although primarily designed for use of laser ablation analysis on geological material this software can be used for any microanalytical technique, including electron microprobe analysis, x-ray fluorescence mapping, scanning electron microscopy and ion beam analysis.\n",

+ " One idea for the future of `autopew` is creating and storing information about coordinate systems and transformations betwen them. Through creating connected networks of coordinate systems, the spatial context of analysis across instruments and images can be automatically determined through aggregating or propogating the transformations.\n",

+ "* **Generating Outputs for a Variety of Instruments**\n",
+ "\n",
+ " Currently `autopew` enables export of coordinates in a few simple formats, and one vendor-specific format (`.scancsv` for Chromium laser ablation navigation software), but where these formats are text based (i.e. not binary proprietary formats) we could readily write reading and writing functions. While the coordinate transforms are relatively format agnostic (as long as it can be read..), these functions are required to make the software practical for use in other labs.\n",
+ "\n",
+ "* **3D Affine Transforms to Keep Focus/Surface Height Context**\n",
+ "\n",
+ " Currently `autopew` only works in 2D, but with a bit of an upgrade we could also store 3D coordinate systems including a 'focus' or z coordinate which are useful for microscale analysis (e.g. especially SIMS). This could probably be implements as 2D + a 1D tilt, given we are typically working on approximately 2D surfaces. "
