.MAT file output by Holo Batch
If the ‘Save particle statistics (MAT)’ checkbox was selected, a MATLAB .MAT file will be created. The .MAT file can only
be opened up in MATLAB. It contains a structure called PartStats. It has dimensions N

17, where N is the number of
particles detected in the ROI.
The 10 columns have the following information about each particle:
Column # Particle Property Unit
1 Particle Area based on pixel count

The Convex Area is the area, based on pixel count, of all pixels within the convex hull of the particle. The convex hull is the smallest polygon that
can contain the particle.
