Thank you very mucy for your reply. The input I used was as follows;<div>&GLOBAL<br> PROJECT vib # #<br> RUN_TYPE VIBRATIONAL_ANALYSIS # # MD ## GEO_OPT ##<br> PRINT_LEVEL LOW<br>&END GLOBAL<br>&VIBRATIONAL_ANALYSIS<br> THERMOCHEMISTRY<br>&END VIBRATIONAL_ANALYSIS</div><div>.</div><div>.</div><div>.</div><div>Shall I use the following input instead of the above? Then, Wouldn't there be a need for a program like Travis?;</div><div>&GLOBAL<br> PROJECT vib # #<br> RUN_TYPE VIBRATIONAL_ANALYSIS # # MD ## GEO_OPT ##<br> PRINT_LEVEL LOW<br>&END GLOBAL<br>&VIBRATIONAL_ANALYSIS<br><b> <font color="#000000">FULLY_PERIODIC T</font></b><br> THERMOCHEMISTRY<br>&END VIBRATIONAL_ANALYSIS<br></div><div><br></div><div>Best</div><div>Cobra<br><div><br><br></div></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">19 Mart 2022 Cumartesi tarihinde saat 12:38:18 UTC+3 itibarıyla tkuehne şunları yazdı:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div style="word-wrap:break-word;line-break:after-white-space">Dear Cobra, <div><br></div><div>both options are possible.
