 -'''Pair  indexing:''' new file series can result from the processing of primary series. For a sequential processing limited to a single file, the output index naturally reproduces  the input index. Other processing functions involve pairs of input files, for instance Particle Imaging Velocity from image pairs. In a simple series, the result from the two primary fields *_i1 and *_i2 is then labeled as *_i1-i2 with the file extension indicating  the output format. More generally,  the result from any processing involving a range of primary indices from  i1 to i2  is  labeled as _i1-i2.  If i1=i2 or j1=j2, the two indices are merged in a single label i, or j respectively.
 
--'''Nomenclature types:''' The ''nomenclature type'' is defined as the character string representing the index for the first file  in the series, for instance '_1' for a single indexing and '_1-2' for a  pair indexing, '_1_1' for a double index series. The second index j can be also represented as a letter suffix, for instance '01a'.  For a field series in a single file, like a movie, the  nomenclature type is defined as '*'. The functions ''fullfile_uvmat.m'' generates a file name from a root name, four numerical indices i1,i2,j1,j2 and  the ''nomenclature type''. The reverse operation, splitting a name into a root and indices while detecting the ''nomenclature type'', is performed by the function ''fileparts_uvmat.m''. The function ''find_file_series.m'' is also needed to scan the whole file series, leading to a possible adjustement of [wiki:NomType the nomenclature type (for instance distinguishing '_001]' from '_1' when the file with index 1000 has been opened). Once the nomenclature type has been detected by the browser of '''uvmat.fig''', it is displayed in the edit box '''[!NomType]''' and used to generate all file names when the series is scanned.

  * 'Campaign' corresponds to a series of experiments obtained by varying a given set of physical parameters. A set of  parameter names (with units) is expected to be associated to a campaign. A project may involve several campaigns corresponding to different configurations, hence different relevant parameters. For a single configuration, 'Campaign' can be at the top of the data tree, without an additional 'Project' level. The uvmat package does not manage levels above 'Campaign'.
  * 'Experiment' is a directory containing all the data for a particular experiment, defined by a choice of values for the physical parameters.
- * '!DataSeries' contains an image series or movie from a camera, or more generally a data series from a device. Its name must correspond to the device and remain the same for all the experiments using this device. The results from data processing, as provided by 'civ' or 'series', are stored at the same level in a !DataSeries directory, named from the source one with a extension specific to the processing program, for instance .civ for civ.

 '''Mirror data trees''' can be created to process a source data set in read only mode, to preserve the safety of the data source, and to allow several users to work in parallel without interference. This is done by opening the source Campaign with the menu bar option Open/browse campaign from uvmat. Select the source campaign directory with the browser. Then the GUI 'browse_data' appears. Then press 'create_mirror' and select the directory which must contain the mirror Campaign. A set of directory is then created for each experiment, in which are created symbolic  links to the !DataSeries directories. Data processing then results in real !DataSeries directories created in the Experiment directory.  An xml mirror.xml is created inside the directory mirror to mark its role; This xml file contains  the path and name of the source directory under the label <!SourceDir>. The mirror directory can be regularly updated by pressing the button 'update_mirror'.
