Dear Root experts;
I stuck in converting the magnetic field data in root file. I have written a code (from an example given in root forum) but am receiving segmentation fault.
My data file has 6 columns and 20000 lines. I am unable to proceed now. Please help me.
For the sake I am attaching herewith the c and data file.
field.C (608 Bytes)
field.txt (1.6 KB)
The error I am getting is as:
*** Break *** segmentation violation
There was a crash.
This is the entire stack trace of all threads:
In your “field.txt” file, make sure that the values are separated by at least one space character.
TFile *f = new TFile("MATRIX.root", "RECREATE");
TTree *t = new TTree("ntuple", "data from the MATRIX file");
TH1F *h = new TH1F("h1", "x distribution", 100, -4., 4.);
delete f; // automatically deletes t and h, too
Thanyou so much … It is Solved … A hug … Gracias …
