normASRcounts: NORMALIZED ALLELE SPECIFIC READ (ASR) COUNTS FOR AN...

In ISoLDE: Integrative Statistics of alleLe Dependent Expression

Description

normASRcounts_file.txt: A tab-delimited text file containing the normalized values of ASR counts for an experiment with more than two replicates.
normASRcounts.rda: the normASRcounts_file.txt loaded into a data.frame by the
readNormInput function.

Format

normASRcounts_file.txt: A tab-delimited file.
normASRcounts.rda: A data.frame.

Details

Each line represents a feature (e.g. a gene or a transcript).
Each column represents the number of allele-specific sens reads from either
the paternal or maternal parent for a given biological replicate, so that
you expect to have two columns per biological replicate.
Values in the matrix are normalized (RLE method) ASR counts.
In case of double input, columns must be in the same order in both raw and normalized ASR counts files.
The normASRcounts_file.txt file should be read and checked by the readNormInput function.

Note

A minimum of two biological replicates per cross is mandatory, however, we strongly recommend to use more than two replicates per cross. This enables a better estimation of variability and to use the bootstrap method to perform the statistical test (see the isolde_test function).
