Using Fortran 77, I'm trying write a program which will read in the coordinates of the atoms in a molecule from this input file: 21 Aspirin C 0.8641 0.1885 -0.0550 C 1.6904 1.2832 -0.0518 C 3.0579 1.1437 -0.0197 C 3.6120 -0.1296 0.0167 C 2.7571 -1.2117 0.0051 C 1.3999 -1.0697 -0.0319 C 3.8348 2.4466 -0.0147 O 3.1949 3.5035 -0.0635 O 5.2264 2.5396 0.0432 O 5.0391 -0.2600 0.0701 C 5.8568 -1.4155 0.2362 O 5.5015 -2.5866 0.4359 C 7.3030 -1.1536 0.2016 H -0.1283 0.3101 -0.0742 H 1.2910 2.1997 -0.0732 H 3.1452 -2.1331 0.0245 H 0.8059 -1.8741 -0.0419 H 5.4969 3.4603 0.0349 H 7.8008 -2.0121 0.3247 H 7.5452 -0.5201 0.9364 H 7.5482 -0.7503 -0.6801 The eventual aim is to calculate interatomic distances and the like, but for the moment I'm having trouble reading the numbers in correctly. My current program looks like this: PROGRAM Aspirin REAL ARRAY1(1:21,1:3) OPEN(UNIT=10, FILE='aspirin.xyz', STATUS='old') READ (10,5),((ARRAY1(I,J),J=1,3),I=1,21) PRINT *,'Array:' PRINT 6,((ARRAY1(I,J),J=1,3),I=1,21) 5 FORMAT(1X,F8.4,F8.4,F8.4) 6 FORMAT(F8.4,F8.4,F8.4) PAUSE END This prints out the array perfectly when I deleted the two lines above the array in the input file; unfortunately, I don't know how to start reading on the third line. I've tried reading in two blank lines(using //) in the read statement, but this doesn't work since they don't have the correct format. I've tried inserting // into the format state, but this skips two lines between each record. I've tried assigning two variables A and B as character strings for the first two lines, but I can't put them in the same READ statement then as the format's wrong, and if I put it in a separate statement the array tries to read from the beginning of the file anyway. I even tried reading in the array for i=3:23, but again the format was wrong for the first two lines and it wouldn't work. Basically, what it boils down to is that there must be a way to specify reading an array from a part of a file other than the beginning, but I don't know what it is. Any help would be gratefully appreciated!
