Dear all,


I was able to split my macro and run my simulations on a cluster, but I
could not merge my root files. I get the following error:

Error in <TFile::TFile>: file root2.root does not exist         (I don't
get
the message for root1.root)
Not a readable file root2.root - exit!

I checked the root2.root output file using ROOT and everything seems to
be
normal.

What can be the problem?

Any suggestion and help will be appreciated!

Thank you,

Didar

Hello all,

I launch the example benchSPECT and get two files, a .hdr and a .sin.
How can I view the .sin file? What's the precision of .sin file, uint16
or float? I try matlab's interfileread function
img=interfileread('projec.hdr'), but it shows?Invalid expression in line
29 of projec.hdr.
line 29 of projec.hdr:? !scaling factor (mm/pixel) [1] := 0.904

When I use fread, all the data I get is zero. How can I get the
projection image?

Thank you!
