Hello all, I have a school assignment in Biology but I seem to be unable to begin... What I was given is something like the following : HELIX1: x y z A 1 1.115 8.537 7.075 B 2 2.745 5.280 7.165 C 3 0.777 3.267 7.329 D 4 1.610 5.225 10.885 E 5 0.296 5.263 10.912 HELIX2: K 1 0.696 13.041 22.357 L 2 1.152 11.081 23.082 M 3 2.200 17.590 18.424 What I must do is : take each atom from each helix (for example atoms A, B, C, D, E from helix1 , atoms K,L,M from helix2) and calculate the distance from all other atoms of the remaining helices. An example : 1) Take atom A from helix1 2) Calculate distance with atom K from helix2 3) Calculate distance with atom L from helix2 4) Calculate distance with atom M from helix2 In order to calculate the distance ,for example, between A(helix1) and K(helix2), I use the formula: distance = (XaXk)^2 + (YaYk)^2 + (ZaZk)^2 So, what I need to store is : x,y,z for each atom then, using the formula above ,I will calculate the distance... I don't know if I need a hash of arrays, an array of hashes or something more or less complicated... Any help?
