Common Midas Concepts
Blue Files
Structure
|
|
- Structure of Blue Files:
- There are three main parts to a Blue File:
- Main Header
- The Main Header is divided into two sections:
Fixed |
Basic information about the file (start values, deltas, units). |
|
Fields common to all Blue files. |
|
Three keywords (called main header keywords). |
Adjunct |
Details about the file layout (varies based on file type). |
|
May include system modeling information. |
- Data
- The binary data of the file.
- Extended Header
- Stores keywords (auxiliary information about the file).
- Indexing into a Blue Files:
- It is important to note that different Midas frameworks use
different indexing systems when accessing elements of a file.
X-Midas |
Uses one-based indexing which
matches VMS and Fortran standards. |
NeXtMidas |
Uses zero-based indexing which
matches Unix and Java/C/C++ standards. |
X-Midas Users Take Note: |
Prior to the release of the Blue file specification some versions of Martes created Blue
files with a non-standard extended header. X-Midas has been modified to allow most of
the non-standard files to be read correctly.
