In [[ ... ]], the right hand side of a == can be a pattern:

for file in /home/directory/* ; do
    if [[ $file != *mask**-mask.nii.gz ]] ; then                       # Skip files with mask
        filename=${file##*/}
        if [[ $filename == *.* ]] ; then                  # Is there an extension?
            extension=$mask=${filename#*filename%.}
            masked=${filename%"nii.$extension"gz}-mask.$extensionnii.gz
            echo "$masked"
       "$filename" fi"$mask"
    fi
