Data Formats

SEA accepts three types of data files: expression, covariates and annotation. Data files are always tab-delimited files. strange symbols (such as % , &, /, # , etc) and quotation marks (“”) should be avoided in labels and gene names. Also the presence of spaces is not recommended.
We next explain each data file in detail:

*Data: txt file with expression data, genes in rows, arrays in columns. The file must contain an additional row with sample names and a column with gene names.

gene_10.180.530.43-0.99-2.45-1.181.432.320.32
  • Covariates: txt file with experimental design information, containing as many columns as arrays and as many rows as experimental factors. Each cell contains the value of the array in the experimental factor. E.g:
