# pascat_SCA_by_gene.csv
Somatic Chromosomal Alterations (SCA)
2.5M Illumina SNP array copy number and copy neutral loss of heterozygosity calles made
by a modified version of the ASCAT algorithm, by Gene.

For each sample and each SCA type, the number of bases of the specified SCA
type are shown per annotated gene.  Note: HighGain is defined as any copynumber
call for a segment >= 6

# Columns:
HugoName {varchar} = Gene name
coding {bool} = True if this gene codes for a protein
DNANum {varchar} = Sample unique identifier to tie with other data tables
intA/intB {integer} = integer copy number of each allele, matching what is in
    pASCAT_SCA.csv.
sca_key {varchar} = SCA type per segment, matching calls made in custom
    xili calling algorithm.
tx_coverage_percent {int} = the fraction of nucleotides in the transcripts for
    this gene covered by the sca specified in sca_key.
