Hello, I am using GeneSpring which gives array information in three columns: Block, Column, Row. I had a question concerning the use of maPrintTip and maPlate. I am unable to find a way to manually input my blocks(24), columns(16) and rows(17) into maPrintTip. I would like this information to be input in marrayLayout(either manually or through a command), and i am unsure how to do this. Currenty, maPrintTip appears to assign those values, is there anyway that I can change this, or do I need to sort my data accordingly before I input it? (i.e. why isn't maPrintTip slot accessible?) My second question concerns the difference between maPrintTip and maPlate. I am confused as to what each of these varialbes represents and therefore what array data should go into each. For example, should I set maPlate equal to a given column in my mfile, and if so should that column refer to my array block, row and or column? Thank you. -Ali

Hi Alison, maPrintTip refers to the print-tip or pins informations and that usually corresponds to the number of Blocks (in gpr files). However, maPlate refers to the 384 well plate that the probes initally came from. You can calculate this from the layout information using the function maCompPlate. Hope I answer your question.
