  • Matrix rows correspond to genes and matrix columns correspond to conditions (arrays).
  • All the data items must be separated by tabulators.
  • There is no special character for missing values, simply leave these places empty.
  • All lines beginning with "#" are treated as commentaries. The first one with #NAMES is mandatory.
  • A period/full stop (never a comma) is used as the decimal point (6.57, not 6,57).
  • Thousands separators should not be used (8665, neither 8.665 nor 8,665)
