util.merge_tiffs does not look for files in a folder

[gminami]

When I try to read a sequence of files in a folder (in this case, "data"),

params = {
    'image_path': './data/',
}

"merge_tiffs" seems to find files in the root folder, instead of the 'image_path'.
img = util.merge_tiffs(params['image_path'], './autofluor.tiff')

/root/.local/lib/python2.7/site-packages/ndreg-1.0.0-py2.7.egg/ndreg/util.pyc in merge_tiffs(path_to_tiffs, filename)
171
172 # now lets go through them and make a tif
--> 173 combined_tiff = sitk.ReadImage(files)
174
175 # now save the tiff

/usr/local/lib/python2.7/dist-packages/SimpleITK/SimpleITK.pyc in ReadImage(*args)
8330
8331 """
-> 8332 return _SimpleITK.ReadImage(*args)
8333 class HashImageFilter(ProcessObject):
8334 """

RuntimeError: Exception thrown in SimpleITK ReadImage: /tmp/SimpleITK/Code/IO/src/sitkImageReaderBase.cxx:74:
sitk::ERROR: The file "181023_10-22-52_GM0322_C00_z0000.ome.tif" does not exist.

I can read this tiff file if I set the 'image_path' as './data/181023_10-22-52_GM0322_C00_z0000.ome.tif' and run img = util.imgRead(params['image_path']) or img = sitk.imgRead(params['image_path']).

@gminami Thanks for bringing this to my attention! I believe I've fixed this issue with the most recent commit. If you pull the most recent version of the neurodata/ndreg docker image, that issue should go away. I corrected this bug in an earlier version of ndreg but hadn't updated the Docker Image.
