SAM_INPUT reads the raw files containing observations intensities and names.
SAM_INPUT (INTENS_FILE, NAMES_FILE) set the global arguments DATA and GENE_NAMES by the content of respectively INTENS_FILE and _NAMES_FILE , files that contain respectively observations' expression values and names.
INTENS_FILE is assumed to be in this format :
- the file contains neither row names, nor column names;
- each row I gives the full data for the I-th observation;
- each column J gives the full data for the J-th experiment (sample);
- for each row, two consecutive fields are separated by one tabulation.
NAMES_FILE is assumed to be in this format :
- the file has the same number of rows as the INTENS_FILE ;
- the file has one and only one column.
