I have a tpr-files.dat containing 5 tpr files as it:
Also the pullf-files.dat is in accordance with tpr-files.dat.
But when I run g_wham and visualize the histo output, I see only one curve and not 4 curves which are expected to have appropriate overlaps! Would you please let me know how come? Is it usual to get one curve from each histo.xvg?
Thanks for your suggestions. I appreciate you in advance.

Then a file named "tpr-files.dat" does not exist in the working directory.
Check for typos and the existence of the file.
