Error in plotting Iso surface at a particular energy

[Gargee-123]

Dear Developers,

Thank you for the b4vasp package, this has been very helpful. I have some question regarding Fermi Surface plotting. I have done Fermi Surface Unfolding and also Iso-surface cuts at a particular energy other than Fermi energy. Many such cases it worked perfectly. I have come across one error for 4 such Iso surface cuts. I am showing here the error :

Selected all orbitals :: s, py, pz, px, dxy, dyz, dz2, dxz, x2-y2

             reading PROCAR[.prim] file(s)

I have checked the b4vasp file, and found the section where I am getting the error. I shall be grateful if you can suggest me something to fix the error.

if [ $(sed -n 20p "temp$INPAR"|grep -Eic "true") -eq 1 ];then mkdir -p "$datdir/bandindexplot";fi

specfun=sed -n 22p "temp$INPAR"|grep -Eic "*true*" if [ $specfun -eq 1 ];then rm -f $datdir/$fsurspecfile*;fi ninterval=grep '#interval' $filedir | awk '{print $2}'

Kind regards Gargee
