DELPHES stops at "Reading standard input"

[Viesturs]

I run Delphes as:

./DelphesHepMC cards/delphes_card_CMS.tcl output_test2.root

After hours of waiting it does not proceed further than the step

Reading standard input

What standard input is it reading? What is going on? What to check?

[Pavel Demin]

./DelphesHepMC cards/delphes_card_CMS.tcl output_test2.root

This command isn't correct. Please try the commands from the WorkBook/QuickTour.

What standard input is it reading?

Some information about standard input can be found at the following links:

​https://en.wikipedia.org/wiki/Standard_streams

For DelphesHepMC to read data from the standard input, its standard input must be connected to the standard output of another program using a pipe:
