Will store in the cell array files the names of the models in volume one that include the string 'vesicle' in their filenames (excluding the path). The dynamo_catalogue_models offers a simplified syntax and some more options for retrieval of model files:įiles = dcmodels('testCatalogue','i',1,'nameContains','vesicle') Would go to the cellarray o.results, fetch the element in position 2 (which is a string), read the file named as that string, and create in memory the object oneModel, which should be a 'live' model object that can be edited. Alternatively, you can read them separately, or read one at a time: Will create a cell array called myModels, where each element is result of reading one model file. If you want to bring the models into the memory to operate on them you need to read the files. Note that, like an ordinary array, rows of a cell array are. They are just strings, each one defining a the name of a model file. create a 4-by-5, two-dimensional cell array and store the information listed in 1, page 191. Note that elements in the cell array extracted from the catalogue m圜atalogue with this command are not model objects. Thus, it is convenient to have a sensible naming convention while you create your models inside the tomograms, as it will facilitate accessing them if required on a later stage. With some practice in parsing strings in Matlab, you can extract a new cell array from a previous cell array, greping only the cell array elements that include some given string in their name. For example, you can specify the number of header lines in the file, the expected number of variables or columns, or a range of data. C readcell (filename,Name,Value) specifies options using one or more name-value arguments. matrix indices in a Matlab array or matrix. C readcell (filename) creates a cell array by reading column-oriented data from a text or spreadsheet file. Note that you can grep model files from only selected volume indices: array, character vector, or cell array of character vectors. The object o.results is a cell array and you can use loops that iterate through it. So that the order will show on screen the names of all the models inside the catalogue m圜atalogue and puts them into the cellarray o.results. -ws o : put the results in a workspace variable ( -ws) arbitrarily called o.-l m : on each visited volume, list ( -l) all the models ( m).-i * : visit all ( *) volume indices ( -i).The names of the model files in a catalogue can be easily extracted with the command line dcm utility. Individual elements can be added through the ) Įxtracting model files from a catalogue Through dcm varTypes specifies the data types of the variables. sz is a two-element numeric array, where sz (1) specifies the number of rows and sz (2) specifies the number of variables. Will just write the string hello in the Matlab desktop ( or in the Dynamo standalone console). T table Size,sz,VariableTypes,varTypes) creates a table and preallocates space for the variables that have data types you specify. This example shows basic techniques for creating arrays and matrices using MATLAB. 2.2 Extracting model files from a catalogueĬreates an empty cell array called a in the memory workspace.Ĭreates a cell array that contains the strings hello and bye, so that.2.1.1 Safe execution of loops on cell arrays.
