Hello, I'm a Summer Student and I've a problem with root. I would like to read a data file like this: 25 ext probe 1 21.93 1052989373314 26 ext probe 1 19.95 1052989373362 27 ext probe 1 20.25 1052989373418 28 ext probe 1 20.40 1052989373465 29 ext probe 1 20.36 1052989373517 30 ext probe 1 19.99 1052989373620 31 ext probe 1 21.17 1052989373683 In order to do this, I have written a script: { gROOT->Reset(); int id; char name1[10]; char name2[10]; int type; float measure; int timestamp; char temp[200]; FILE *apre; apre = fopen("extprobe.dat","r"); while(fgets(temp, sizeof(temp), apre) !=NULL) { sscanf(temp, "%d %s %s %d %g %d", &id, &name1,&name2, &type, &measure, ×tamp); printf("%d %s %s %d %g %d\n", id, name1,name2, type, measure, timestamp); } fclose(apre); } Alas, it doesn't work, because it can't manage to read the last number of each line (it's too long). Could you give any hint? Thank you very much. Livia Ferro
