This part describes non-obvious terms used in this package.
- affxparser
The name of this package.
- API
Application program interface, which describes the
functional interface of underlying methods.
- block
(aka group).
- BPMAP
A file format containing information
related to the design of the tiling arrays.
- Calvin
A special binary file format.
- CDF
A file format: chip definition file.
- CEL
A file format: cell intensity file.
- cell
(aka feature) A probe.
- cell index
An integer that identifies a probe uniquely.
- chip
An array.
- chip type
An identifier specifying a chip design
uniquely, e.g. "Mapping50K_Xba240"
.
- DAT
A file format: contains pixel intensity
values collected from an Affymetrix GeneArray scanner.

SNP arrays have either two or four groups per unit, one for each of
the two allele times possibly repeated for both strands.
- MM

- PGF
A file format: probe group file.
- TPMAP
A file format storing the relationship between (PM,MM)
pairs (or PM probes) and positions on a set of sequences.
- QC
Quality control, e.g. QC probes and QC probe sets.
- unit
A probeset.
- XDA
A file format, aka as the binary file format.
