Due to a mixup in processing, I require to invert the order of the well numbers from a 96-well plate
Python, 23 lines
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
#!/usr/bin/python #for inverting the plate order when mixups occur! ##e.g. input file looks like ##B1 B3 B5 B7 B9 B11 B13 B15 B17 B19 B21 B23 ##D1 D3 D5 D7 D9 D11 D13 D15 D17 D19 D21 D23 ##F1 F3 F5 F7 F9 F11 F13 F15 F17 F19 F21 F23 ##H1 H3 H5 H7 H9 H11 H13 H15 H17 H19 H21 H23 ##J1 J3 J5 J7 J9 J11 J13 J15 J17 J19 J21 J23 ##L1 L3 L5 L7 L9 L11 L13 L15 L17 L19 L21 L23 ##N1 N3 N5 N7 N9 N11 N13 N15 N17 N19 N21 N23 ##P1 P3 P5 P7 P9 P11 P13 P15 P17 P19 P21 P23 input=open('xa','r') L=input.readlines() #reads lines into list L.reverse() #reverse rows for row in L: ## print row splitrow = row.split("\t") splitrow.reverse() #reverse column newwell= newwell.extend(splitrow) print newwell
inputfile name is 'xa' last print statement needs working.. but its good enough for me
I don't understand the newwell variable. It seems that you could just cast splitrow into a list after the reverse.
can also make it shorter, and take the filename from the command line.
Thanks for the comments! Matthew Wood: It is true I can immediately print the reversed row. I wanted to put all the wells in the correct order into newwell so that I might possibly do something to it.
brent pedersen: Thanks for the tip! will update the link .. it was a quick hack so not sure if I need to do this again. I was surprised that no one posted this recipe before.
