For spatial clustering methods, ClusterSeer can import text files with or without a header.
If you do not use a header, ClusterSeer requires the data in a particular order (for example x, then y , then case count, and so on). If you use a header, ClusterSeer can be more flexible about file structure. This header is similar to that used in BioMedware's boundary detection and analysis software, BoundarySeer.
When you use a header, you can select columns from the data file for use in an analysis.
The headers consist of 4 lines of text above the data. These lines describe the contents of the file. The lines describe the coordinate system (geographic or planar), data type (not used in ClusterSeer), missing data (not used in ClusterSeer) and Variable/Field names. ClusterSeer's interpretation of the header is not case-sensitive.
ClusterSeer will ignore header entries for data type and missing data. For variable/field names, the names must be separated by commas.
Header lines can be in any order and blank lines are not a problem.
Coordinate system: geographic
Data type: numeric
Missing data: -99
Variable names: x, y, population at risk, cases, name
Field names: pop, cases, name, x, y
Coordinate system: planar
