Commands work from Shell script, but not from command line?

Question

I quickly looked for it before posting, but could not find such posts. Let me know if they exist.

---

Executable commands seem very simple. The directory listing is used as input to the function.

The directory contains a bunch of files named "epi1_mcf_0 ###. Nii.gz"

Command line version (bash is executed when it is executed):

fslmerge -t output_file `ls epi1_mcf_0*.nii.gz`

Shell version of the script:

#!/bin/bash
fslmerge -t output_file `ls epi1_mcf_0*.nii.gz`

A command line error, but the shell script works fine.

The error message refers to the function, but it is enabled in any case.

** ERROR (nifti_image_read): failed to find header file for 'epi1_mcf_0000.nii.gz'
** ERROR: nifti_image_open(epi1_mcf_0000.nii.gz): bad header info
Error: failed to open file epi1_mcf_0000.nii.gz
Cannot open volume epi1_mcf_0000.nii.gz for reading!

I was very upset by this problem (moreover, after I realized that there is a way to make the team work).

Any help would be appreciated.

(Or is there a general consensus that the problem needs to be looked for in the "fslmerge" function?)
