[Neuroimaging] Reading map object as having no length

[Stephen Suss]

Hello, community

I have some inherent Nipype code that I edited and am running on a
Linux-based operating system. I'm using Nipype version 1.8.5 and Python
version 3.7. The code is crashing (error below), and understandably because
Python 3 cannot read map objects as having a length. I am wondering why
this error is occurring within FSL and if there is a way around it.


Traceback:
Traceback (most recent call last):
 File
"/home/data/madlab/envs/emuR01_madlab_env/lib/python3.7/site-packages/nipype/interfaces/base/core.py",
line 398, in run
   runtime = self._run_interface(runtime)
 File

line 218, in _create_ev_files
   if len(amplitudes) > 1:
TypeError: object of type 'map' has no len()




The above exception was the direct cause of the following exception:


Traceback (most recent call last):
  File "emu_fsl_frstlvl_fconnect.py", line 539, in <module>
