Sorry I meant IT DID NOT WORK FOR ME. 1-Also may I ask for the latest denchar manual or latest tutorial? I could not find what you have recently suggested 2-How to read WFSX files? Because I thought I should be reading from the EIG files where the number represents the eigenvalue number from lowest to highest. Thank you!

If you have a WFSX file with many wavefunctions, it is already too late. You can re-run Siesta with those options (re-using the density-matrix to save cpu time). Alternatively, if you have a modern version of Denchar (later than August 2019 approximately), you can use the following feature: Wavefunctions can be selected by means of the -k and -w command line arguments. For example, denchar -k 3 -w 4 file.fdf will plot only the wave-function with (original) index 4 of the third k-point in the (WFSX) file.
