Error in Optimize!

[mdhe1248]

Pleae help me to solve this error:

julia> optimize!(ϕs_new, ϕsi, ap, λt, mmisc);
ERROR: Not yet implemented for incommensurate knots

Below is more detailed explanation:
I was trying to optimize a deformation matrix ϕs_new.

julia> optimize!(ϕs_new, ϕs, ap, λt, mmis)
ERROR: MethodError: `maxshift` has no method matching maxshift(::Float32)
 in optimize! at /home/donghoon/.julia/v0.4/BlockRegistration/src/RegisterOptimize.jl:522

Here, maxshift requires a type like this: CachedInterpolations.CachedInterpolation{RegisterCore.NumDenom{Float32},3,7,(5,5,3)}
The type of mmis was Array{Float32,8}.
Therefore, Tim converted mmis.

using Base.tail
ND = NumDenom{eltype(mmis)}
mmisr = reinterpret(ND, mmis, tail(size(mmis)));
N = ndims(ap)
mmisc = cachedinterpolators(mmisr, N, ntuple(d->(size(mmisr,d)+1)>>1, N));

There were still errors:

julia> optimize!(ϕs_new, ϕs, ap, λt, mmisc)
ERROR: MethodError: `compose` has no method matching compose(::RegisterDeformation.GridDeformation{Float32,3,Array{FixedSizeArrays.Vec{3,Float32},3},LinSpace{Float64}}, ::RegisterDeformation.GridDeformation{Float32,3,Array{FixedSizeArrays.Vec{3,Float32},3},LinSpace{Float64}})
Closest candidates are:
  compose{T1,T2,N,A<:Interpolations.AbstractInterpolation{T,N,IT<:Union{Interpolations.InterpolationType,Tuple{Vararg{Interpolations.InterpolationType}}},GT<:Union{Interpolations.GridType,Interpolations.NoInterp,Tuple{Vararg{Union{Interpolations.GridType,Interpolations.NoInterp}}}}}}(::RegisterDeformation.GridDeformation{T1,N,A<:Interpolations.AbstractInterpolation{T,N,IT<:Union{Interpolations.InterpolationType,Tuple{Vararg{Interpolations.InterpolationType}}},GT<:Union{Interpolations.GridType,Interpolations.NoInterp,Tuple{Vararg{Union{Interpolations.GridType,Interpolations.NoInterp}}}}},L}, ::RegisterDeformation.GridDeformation{T2,N,A<:AbstractArray{T,N},L})

It was something related to interpolation:

julia> ϕsi = map(RegisterDeformation.interpolate, ϕs);

Still, all error have not been disappeared.
