1.1.1.1 Description
The Material file describes the composition of the material formulation and is not included in the ISA-TAB specification. The Material file is an important file that is designed to allow for nanomaterial comparison across nanotechnology resources. The Material file also allows for the association with an optional Structure file for representing the 3D structure of the nanomaterial.
An investigation typically involves the preparation of multiple materials. These materials could be of the same chemical composition (same type and amount of chemical components in the sample) or of different chemical compositions. Materials having the same chemical composition should be described using one Material file. Materials of different chemical composition could be described separately using multiple materials files or described in a single material file.
1.1.1.2 File Format
The Material file format leverages a vertical based spreadsheet format with columns representing multiple values. In the example subset of the Material file below, column A indicates the field names and columns B and C are field values.

1.1.1.3 nano-TAB Extensions
Since the Material file does not exist in the ISA-TAB standard, the entire file is considered an extension. This file is described in detail in Section 4.
