error in twdtwApplyParallel "subscript out of bounds" the same as the unsolved issue #39

Dear Victor,

I am trying to run your code for a TWDTW in a sample study area. I'm using Sentinel-1 data, for 29 images throughout 2018.

All works fine until I use the function "twdtwApplyParallel". It throws an error:

Error in [<-(tmp, rows, , value = d$value$value[[l]]) : subscript out of bounds

When running with the "twdtwApply" function, again, it fails with the error:

Error in [<-(tmp, rows, , value = B[[l]]) : subscript out of bounds

I have read the issue "error in twdtwApplyParallel "subscript out of bounds" #35" opened by n-verde. After adding the filepath variable to the twdtwApplyParallel and twdtwApply functions removes the error, but the code fails at the same functions (twdtwApply and twdtwApplyParallel) with the new error:(The same as n-verde)

Error in rng[1, ] : incorrect number of dimensions.

I have examined my data ('changsha_SAR_stackBYmatlab.tif' & 'changsha_doy_stackBYmatlab.tif') and there is no N/A in them. So I can't remove the N/A in my data to run the function just like n-verde.

Here is my code&data: https://drive.google.com/open?id=1tj-kj2wjVHR4bCFe2-IO4MlqoDV2wQ8k

Any idea what might be wrong?

Thank you very much,

Panbh
