Hi,I meet the same problem,but I don’t want to save the temporary file,What should I do?
You have to save the files somewhere and there's an option in ants.registration
which allows you to specify the location.
Hello, I'm running into the same issue. I want to save the .mat files in a specific, non-temp location, but I can't find the option to specify the location.
When I ran help( ants.registration )
, I get the following:
`Help on function registration in module ants.registration.interface:
registration(fixed, moving, type_of_transform='SyN', initial_transform=None, outprefix='', mask=None, grad_step=0.2, flow_sigma=3, total_sigma=0, aff_metric='mattes', aff_sampling=32, aff_random_sampling_rate=0.2, syn_metric='mattes', syn_sampling=32, reg_iterations=(40, 20, 0), aff_iterations=(2100, 1200, 1200, 10), aff_shrink_factors=(6, 4, 2, 1), aff_smoothing_sigmas=(3, 2, 1, 0), write_composite_transform=False, random_seed=None, verbose=False, multivariate_extras=None, **kwargs) Register a pair of images either through the full or simplified interface to the ANTs registration method.
ANTsR function: `antsRegistration`
Arguments
---------
fixed : ANTsImage
fixed image to which we register the moving image.
moving : ANTsImage
moving image to be mapped to fixed space.
type_of_transform : string
A linear or non-linear registration type. Mutual information metric by default.
See Notes below for more.
initial_transform : list of strings (optional)
transforms to prepend
outprefix : string
output will be named with this prefix.
mask : ANTsImage (optional)
mask the registration.
grad_step : scalar
gradient step size (not for all tx)
flow_sigma : scalar
smoothing for update field
total_sigma : scalar
smoothing for total field
aff_metric : string
the metric for the affine part (GC, mattes, meansquares)
aff_sampling : scalar
the nbins or radius parameter for the syn metric
aff_random_sampling_rate : scalar
the fraction of points used to estimate the metric. this can impact
speed but also reproducibility and/or accuracy.
syn_metric : string
the metric for the syn part (CC, mattes, meansquares, demons)
syn_sampling : scalar
the nbins or radius parameter for the syn metric
reg_iterations : list/tuple of integers
vector of iterations for syn. we will set the smoothing and multi-resolution parameters based on the length of this vector.
aff_iterations : list/tuple of integers
vector of iterations for low-dimensional (translation, rigid, affine) registration.
aff_shrink_factors : list/tuple of integers
vector of multi-resolution shrink factors for low-dimensional (translation, rigid, affine) registration.
aff_smoothing_sigmas : list/tuple of integers
vector of multi-resolution smoothing factors for low-dimensional (translation, rigid, affine) registration.
random_seed : integer
random seed to improve reproducibility. note that the number of ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS should be 1 if you want perfect reproducibility.
write_composite_transform : boolean
Boolean specifying whether or not the composite transform (and its inverse, if it exists) should be written to an hdf5 composite file. This is false by default so that only the transform for each stage is written to file.
verbose : boolean
request verbose output (useful for debugging)
multivariate_extras : additional metrics for multi-metric registration
list of additional images and metrics which will
trigger the use of multiple metrics in the registration
process in the deformable stage. Each multivariate metric needs 5
entries: name of metric, fixed, moving, weight,
samplingParam. the list of lists should be of the form ( (
"nameOfMetric2", img, img, weight, metricParam ) ). Another
example would be ( ( "MeanSquares", f2, m2, 0.5, 0
), ( "CC", f2, m2, 0.5, 2 ) ) . This is only compatible
with the SyNOnly transformation.
kwargs : keyword args
extra arguments
Returns
-------
dict containing follow key/value pairs:
`warpedmovout`: Moving image warped to space of fixed image.
`warpedfixout`: Fixed image warped to space of moving image.
`fwdtransforms`: Transforms to move from moving to fixed image.
`invtransforms`: Transforms to move from fixed to moving image.
Notes
-----
type_of_transform can be one of:
- "Translation": Translation transformation.
- "Rigid": Rigid transformation: Only rotation and translation.
- "Similarity": Similarity transformation: scaling, rotation and translation.
- "QuickRigid": Rigid transformation: Only rotation and translation.
May be useful for quick visualization fixes.'

Employs dense sampling during metric estimation.'
- "BOLDRigid": Rigid transformation: Parameters typical for BOLD to
BOLD intrasubject registration'.'
- "Affine": Affine transformation: Rigid + scaling.
- "AffineFast": Fast version of Affine.
- "BOLDAffine": Affine transformation: Parameters typical for BOLD to
BOLD intrasubject registration'.'
- "TRSAA": translation, rigid, similarity, affine (twice). please set
regIterations if using this option. this would be used in
cases where you want a really high quality affine mapping
(perhaps with mask).

transformation, with mutual information as optimization
metric and elastic regularization.

- "SyNRA": Symmetric normalization: Rigid + Affine + deformable
transformation, with mutual information as optimization metric.
- "SyNOnly": Symmetric normalization: no initial transformation,
with mutual information as optimization metric. Assumes
images are aligned by an inital transformation. Can be
useful if you want to run an unmasked affine followed by
masked deformable registration.
- "SyNCC": SyN, but with cross-correlation as the metric.
- "SyNabp": SyN optimized for abpBrainExtraction.
- "SyNBold": SyN, but optimized for registrations between BOLD and T1 images.
- "SyNBoldAff": SyN, but optimized for registrations between BOLD
and T1 images, with additional affine step.
- "SyNAggro": SyN, but with more aggressive registration
(fine-scale matching and more deformation).
Takes more time than SyN.
- "TV[n]": time-varying diffeomorphism with where 'n' indicates number of
time points in velocity field discretization. The initial transform
should be computed, if needed, in a separate call to ants.registration.
- "TVMSQ": time-varying diffeomorphism with mean square metric
- "TVMSQC": time-varying diffeomorphism with mean square metric for very large deformation
- "antsRegistrationSyN[x]": recreation of the antsRegistrationSyN.sh script in ANTs
where 'x' is one of the transforms available (e.g., 't', 'b', 's')
- "antsRegistrationSyNQuick[x]": recreation of the antsRegistrationSyNQuick.sh script in ANTs
where 'x' is one of the transforms available (e.g., 't', 'b', 's')
- "antsRegistrationSyNRepro[x]": reproducible registration. x options as above.
- "antsRegistrationSyNQuickRepro[x]": quick reproducible registration. x options as above.
Example
-------
>>> import ants
>>> fi = ants.image_read(ants.get_ants_data('r16'))
>>> mi = ants.image_read(ants.get_ants_data('r64'))
>>> fi = ants.resample_image(fi, (60,60), 1, 0)
>>> mi = ants.resample_image(mi, (60,60), 1, 0)
>>> mytx = ants.registration(fixed=fi, moving=mi, type_of_transform = 'SyN' )
`
Unless I am missing something, there is nothing here indicating that there is an option to change the save directory. Could you please clarify how to set this option?
outprefix : string output will be named with this prefix.

Thank you - does this change the location that the output will be saved to, or will it still be output to a temp directory?
Outputprefix includes path information
Ok, thank you!
Hi,
After performing a registration, I found resulted transforms are automatically saved in my /tmp/ directory. Is there a way to change this behaviour?
Thanks. Tao
