Thread: Getting an error message: 'ERROR 1301: No data files read in.'

Hi, I keep getting an 'ERROR 1301: No data files read in.' message.

I am using 'respknt' code written by G.Randall to calculate P & S wave
response, which is written in detail in the following link.
http://eqseis.geosc.psu.edu/cammon/HTML/RftnDocs/resp01.html

I downloaded a set of codes including 'respknt' from Charles Ammon's
website, which is as follows.
http://eqseis.geosc.psu.edu/cammon/HTML/RftnDocs/thecodes01.html

I followed all the instructions written in the link, and made a velocity
model 'smp.mod' using 'icmod' and calculated R- and Z- component response,
which are 'smp.mod_sp.r' and 'smp.mod_sp.z', respectively.

When executing 'icmod' and 'respknt', I referred to the following links.
http://eqseis.geosc.psu.edu/cammon/HTML/RftnDocs/icmod01.html
http://eqseis.geosc.psu.edu/cammon/HTML/RftnDocs/resp01.html

However, when I try to read the response files using sac, I get the error
messages 'ERROR 1301: No data files read in.'

I tried to find solutions, but failed.

I would really appreciate it if anyone could suggest a solution to this
problem.

Thanks.
