# nib-diff(1)

Python3 bindings to various neuroimaging data formats

## NAME

nib-diff - Python3 bindings to various neuroimaging data formats

## SYNOPSIS

**nib-diff** \[*OPTIONS*\] \[*FILE* ...\]

## DESCRIPTION

Quick summary of the differences among a set of neuroimaging files

### Notes:

-

  \- difference in data types for header fields will be detected, but

-

  endianness difference will not be detected. It is done so to compare files with native endianness used in data files.

## OPTIONS

- **--version**

  show program's version number and exit

- **-h**, **--help**

  show this help message and exit

- **-v**, **--verbose**

  Make more noise.  Could be specified multiple times

- **-H** HEADER\_FIELDS, **--header-fields**=*HEADER\_FIELDS*

  Header fields (comma separated) to be printed as well (if present)

- **--ma**=*DATA\_MAX\_ABS\_DIFF*, **--data-max-abs-diff**=*DATA\_MAX\_ABS\_DIFF*

  Maximal absolute difference in data between files to tolerate.

- **--mr**=*DATA\_MAX\_REL\_DIFF*, **--data-max-rel-diff**=*DATA\_MAX\_REL\_DIFF*

  Maximal relative difference in data between files to tolerate. If **--data-max-abs-diff** is also specified, only the data points with absolute difference greater than that value would be considered for relative difference check.

- **--dt**=*DTYPE*, **--datatype**=*DTYPE*

  Enter a numpy datatype such as 'float32'.
