stereo.utils.data_helper.merge(*data_list, reorganize_coordinate=2, horizontal_offset_additional=0, vertical_offset_additional=0, space_between='0', var_type='intersect')[source]#

Merge several slices of data.

Parameters:

  • data_list (StereoExpData) – several slices of data to be merged, at least two slices.

  • reorganize_coordinate (Union[bool, int]) –

    whether to reorganize the coordinates of the obs(cells), if set it to a number, like 2, the coordinates will be reorganized to 2 columns on coordinate system as below

    data1 data2
    data3 data4
    data5 …
    … …

    if set to False, the coordinates maybe overlap between slices.

  • horizontal_offset_additional (Union[int, float]) – the additional offset between each slice on horizontal direction while reorganizing coordinates.

  • vertical_offset_additional (Union[int, float]) – the additional offset between each slice on vertical direction while reorganizing coordinates.

  • space_between (Optional[str]) – the distance between each slice, like ‘10nm’, ‘1um’, …, it will be used for calculating the z-coordinate of each slice.

  • var_type – Which claims that _var is intersected by lots of genes from different samples.

Returns:

A merged StereoExpData object.
