I am not sure I understand your workflow. Can you do a print in the variable you import to IDL, then another on the variable you are trying to export for spectra?
Spectra are stored as a one band array in ENVI where the samples are the wavelengths and the lines are the different materials, so samples x lines x 1. If you had to reorganize the array in IDL to perform your analysis, you will need to use REFORM to get the array into the form above to import it as a spectral library.

Thank you very much for your response. I am not sure that I understand your answer, but I will try to respond to your questions. I have a set of spectra with the text file:

Column 1: Wavelength
Column 2: Augite-hypersthene Andesite [igneous-intermediate-solid-andesi2]~~2##255,0,0
Column 3: Fossiliferous Limestone [sedimentary-limestone-coarse-limest1]~~3##0,255,0
Column 4: Rhyolite [igneous-felsic-fine-rhyoli1]~~4##0,0,255
Column 5: Rhyolite [igneous-felsic-solid-rhyoli1]~~5##255,255,0
Column 6: Altered volcanic tuff [igneous-felsic-solid-cup1]~~6##0,255,255
Column 7: Hydrogrossular NMNH120555 [W1R1Bb AREF]~~7##255,0,255
Column 8: Montmorillonite CM20 [W1R1Bb AREF]~~8##176,48,96
Column 9: Kaolinite CM9 [W1R1Bb AREF]~~9##46,139,87

For the specific spectra, I want to Apply MNF to spectra. The text file created by this procedure is the following:
Column 1: Wavelength
Column 2: MNF (Augite-hypersthene Andesite [igneous-intermediate-solid-andesi2])~~2##255,0,0
Column 3: MNF (Fossiliferous Limestone [sedimentary-limestone-coarse-limest1])~~22##0,128,0
Column 4: MNF (Rhyolite [igneous-felsic-fine-rhyoli1])~~4##0,0,255
Column 5: MNF (Rhyolite [igneous-felsic-solid-rhyoli1])~~6##0,255,255
Column 6: MNF (Altered volcanic tuff [igneous-felsic-solid-cup1])~~7##255,0,255
Column 7: MNF (Hydrogrossular NMNH120555 [W1R1Bb AREF])~~28##128,128,0
Column 8: MNF (Montmorillonite CM20 [W1R1Bb AREF])~~31##0,128,128
Column 9: MNF (Kaolinite CM9 [W1R1Bb AREF])~~19##128,0,0

Then I implement the procedure:
ENVI> help, data
ENVI> data = data[0:14,*]
ENVI> envi_plot_data, lindgen(15)+1, data

And in the end, it occurs the error with the variable of y-axis..

Try importing your data as discussed here in the help:
http://www.harrisgeospati...Transform.html#Apply

Your 'data' is not a raster of num_samples x num_lines x 1 band.. I would use Build Spectral library to import your text files to create a spectral library and then apply the forward MNF.

Actually I implemented the builder in order to create the specific spectral library.. And then I apply the forward MNF to spectra..

This was successful? Did you also set the units for the wavelengths?

No, it wasn't successful.. I think that a part is missing regarding the resampling of my spectral signatures with the MNF bands. I am not sure! I will try it again and I will repost for the right results!
