nipype.algorithms.modelgen.SpecifySPMModel: unclear input format for realignment_parameters

Summary

I want to pass a .tsv file to as input to the realignment_parameters argument from SpecifySPMModel, but I think I pass it in the wrong format? It's not clear from the docs what the file should look like (in contrast to e.g. bids_event_file or event_files)

Actual behavior

Node: first_level_analysis.model_specifier
Working directory: /home/johannes.wiesner/work/projects/project_indicate/cache/first_level_analysis/_session_01_subject_INDI1W934_task_faces/model_specifier

Node inputs:

bids_amplitude_column = <undefined>
bids_condition_column = trial_type
bids_event_file = <undefined>
concatenate_runs = False
event_files = <undefined>
functional_runs = <undefined>
high_pass_filter_cutoff = 128.0
input_units = secs
outlier_files = <undefined>
output_units = secs
parameter_source = SPM
realignment_parameters = <undefined>
subject_info = <undefined>
time_repetition = 0.8

    ValueError: could not convert string to float: 'trans_x'

If I read it correctly, the file is parsed using np.loadtxt() and therefore should only be a plain .txt file? What would be the separator there?
