Converting microarray images

Microarray images are generally stored as 16-bit TIFF images (usually around 100Mb in size. An alternative lossy image format is JPEG format, which is still bloated at around 40Mb filesize. Investigating the image size of a typical GenePix derived JPEG image, the pixel size is 4400 × 14300 pixels (72 pixels per inch) with an aspect ratio of 3.25 . These images could be converted to a much smaller thumbnail PNG type image using an appropriate program such as ImageMagick or Gimp which allows batch processing of multiple images a once.
