Chromosome Information – an annotation key to indicate on which chromosome
the loci is located. This information is not needed in the case of organisms that
have only one chromosome.
The locus identifier should be an annotation field loaded with the annotation
during the expression file load in MeV. If the input data is in mev format then the
locus identifier should be a field in the corresponding annotation (MeV .ann
format file). For other formats this annotation should be found in the data file
where each locus id is on the row corresponding to the associated spot
information (annotation and expression data).
(Please see the manual section 4, Loading Expression Data, for information on
file loading for specific file format loading instructions).
The Coordinate Information and Chromosome Information can likewise be
imported with the annotation during the expression file load or a chromosomal
coordinate file can be used to supply the coordinate and chromosomal
information. This optional chromosome/coordinate file has a simple tab delimited
format described below.
Optional Chromosomal Coordinate File
In the case where chromosomal information is not supplied during the initial MeV
file load, an auxiliary coordinate file can be supplied for LEM construction. The
format of the file is a text tab-delimited format with a row for each locus. The
columns have the following order ( [] indicates optional column):
<Locus ID> [Chr ID] <5’ end> <3’ end>
The file should not have a header. Spots in the loaded data set will be ignored if
they map to loci for which location information is incomplete or missing.
The LEM Initialization Dialog
The initialization dialog collects information that indicates where the critical
information for LEM construction resides and provides information about the
nature of the data.
