===Purpose===
Listed below are file readers and tools for importing images.
Run texture analysis on an image or group of images.


===Synopsis===
==File Readers==
*[[camecaeval]] - Assess information in each mass in a Cameca Ion-Tof file.
*[[camecard]] - Read Cameca Ion-Tof file into MATLAB.
*[[lispixrawreadr]]
*[[opotekenvirdr]]
*[[opotektiffrdr]]
*[[rawread]]


:[y,varargout]= texture(img, method, options, varargin)
==Import Tools==


===Description===
*[[clipboard_image]] - Copy and paste images to/from the system clipboard.  
TEXTURE will perform an analysis on any 2 dimensional (m x n pixels) layer of an image or group of images. It loops through input 'img' where mode 3 is considered the variables (slabs of an image) mode and mode 4 is considered the images mode. Any additional inputs to the chosen 'method' must be added after the options input.
*[[image_folder_load]] - Load all image files in a selected directory as cell array of image DSOs.  
 
*[[imageload]] - GUI to select, build, then load a image DSO into the DataSet Editor.
Outputs are 'y' a dataset with each row corresponding to an image and varargout containing any secondary output from the selected method. Outputs for a 'method' must be designated by the user with options.numout. Outputs will be appended together forming one row vector per image. E.G. for 'anglemt' if options.numout = [2 1] then the y{2} and y{1} outputs of 'anglemt' will be concatenated to form the row. Only the first output of a function is used. If there is a second output of a function it is assigned to varargout.
 
Aggregation can be performed across variables (slabs/layers) and or across images. For example, setting options.varmode = 'sum' will sum the layer of an image into one layer.
 
====Inputs====
* '''img''' = image data (matrix or DataSet). The first two modes must be pixels, the third mode must be variables, and the fourth mode must be images.
* '''method''' = texture method ('anglemt' 'autocor_img' 'svd_texture' 'fft_texture' 'semivar').
 
====Optional Inputs====
* '''varargin''' = additional input needed for selected 'method'.
 
====Outputs====
* '''firstout''' = first output is this.
* '''y''' = dataset where each row (spectra) corresponds to an image.
* '''varargout''' = second ouput of a function (e.g. for anglemt this would be 's', the distance scales). Will transform into row vector of cells.
 
===Options===
 
options =  a structure array with the following fields:
 
* '''numout''': [{1}] 1xK vector. Number and order of outputs from selected 'method' to use.
* '''imgmode''': [ {'none'} | 'sum' | 'mean' ] aggregation across images.
* '''varmode''': [ {'none'} | 'sum' | 'mean' ] aggregation across variables.
 
TEXTURE FUNCTION SUB-STRUCTURES
These options can be assigned in their nested form. See the particular function for a full description of available options. For example:
: <tt>options.anglemt.xscale = [1:100];</tt>
