Layers

amics layer structures data from amics structured in layers, which will ultimately affect what the users can visualize and available calculation results users need to be aware of which layer is being viewed in amics as this will affect downstream processing and reporting images the very base layer in this data structure is the image layer, which can contain multiple sublayers of image data these data could include a bse, se, cl, optical camera, or other possible images from the instrument it should be noted that the individual field images are immutable once collected, and the fields can only be overlapped for stitching purposes this layer is currently for navigation and specimen visualization purposes, and the underlying "data" from these images are not used during data reduction and processing segments the segment layer is the first data layer in which users will interact with the data and will affect the final classification and calculations this layer originates from the mla particle mapping mode, which would generate regions of similar bse greyscale, with each of these regions being a segment in the current version of amics (version 3 3 1), the user can delete and change the classification now that amics has multiple analysis modes, the segment layer does not just refer to areas of similar bse, but in the case of matrix mapping mode, each x ray pixel is considered a segment grains the grain layer represents continuous segments with the same classification as with the segment layer, users can delete and change the classification assigned to each grain this layer is also the first layer for meaningful reporting of data, and grains can be extracted individually for visualization, and sorting grains are available for both block and granulated sample types particles the particle layer presents areas of continuous grains that are surrounded by a background classified material currently, the particle layer represents the topmost layer for the particle mapping mode and is only available for granulated samples the particle layer also allows for the most calculation options for reporting frames the frame layer is equivalent to the particle layer but is only applicable for block type samples which were measured by particle mapping mode this layer treats each field of view as a particle, where the field boundary is thought to be the background material caulcation results for frame layers are limited as this layer does not represent aspects of the specimen, but rather measurement conditions layers in amics process selecting layers in process in amics process the results are displayed based on different layers the current active layer will be highlighted in the main ribbon for granulated samples segment , grain , or particle can be selected (see below) however, in the case of block type samples where particles are not separated by the software, the user may choose between segment , grain , or frame layers (in the case of particle mapping data) (fig 64b) new icons requires amics 5 2 0 or newer amics 5 2 is currently in beta testing the released version of amics is {{version}} and can be found with the most recent beta at the docid\ e1faehd1k20uedqhptzlx page manuals for previous versions of the software can be found at the docid\ d2biwe sybowhhdww0anz page
