I have a trouble calculating Duschinsky matrix in GAUSSIAN. The official GAUSSIAN website states that it is possible to calculate it with

Output=Matrix=JK

keyword (https://gaussian.com/freq/ Examples section), however, when I try to run a calculation with the same keywords as in their website, GAUSSIAN .log file states an error:

ERROR: The following wrong keyword(s) have been found:
 OUTPUT=MATRIX=JK

However, I have managed to get vibronic spectrum with a keyword list like this:

%Chk=DPB_gr.chk
# B3LYP/cc-pvtz Freq(ReadFC,FC,ReadFCHT) NoSymm SCRF(Solvent=Cyclohexane) Geom=Checkpoint Guess=Read

FC simulation of UV absorption spectrum for trans,trans-1,4-diphenyl-l,3-butadiene

0 1

SpecHwHm=400 SpecRes=20 InpDEner=0.133

What should I add to my keyword list to get the Duschinsky matrix? I have searched through many pages on the internet, however, I did not find more information regarding this issue. Would be very grateful to get any kind of help regarding this error and thank you in advance for sharing your knowledge.
