Matthew, My bash profile is completely blank. Forgive me, as I am very new to both FSL and computer programing. If I merely enter that path you just gave me, would that fix my issue? Or is source a command that I need to place before it?

This issue only happens when I access Melodic through the terminal. Instead of having the header "Melodic Version 3.14" as it should, it says "/usr/share/fsl/5.0/bin/melodic: error while loading shared libraries: libutils.so: cannot open shared object file: No such file or directory. Also, whether I try to enter 1 input (meaning it is not due to inputting the same subject) or 86 (my n= in this analysis), the following error log pops up:child process exited abnormally > child process exited abnormally > while executing > "exec sh -c "${FSLDIR}/bin/fslnvols $thefile 2> /dev/null" " > (procedure "feat5:updateimageinfo" line 9) > invoked from within > "feat5:updateimageinfo $w $i 1" > (procedure "feat5:multiple_check" line 63) > invoked from within > "feat5:multiple_check .r 0 1 1 d" > invoked from within > ".dialog1.cancel invoke" > ("uplevel" body line 1) > invoked from within > "uplevel #0 [list $w invoke]" > (procedure "tk::ButtonUp" line 22) > invoked from within > "tk::ButtonUp .dialog1.cancel" > (command bound to event) > > Please let me know what could be the issue. Thank you so much.
