In tetracam tutorial (https://support.pix4d.com/hc/en-us/articles/115005187543-How-to-process-a-Tetracam-dataset) the camera band definitions are said to be taken by MCA file of the camera. However pix4d does not ask for the MCA file after adding images. After 12 channel Macaw images are loaded, pix4d can only detect one Group “Grayscale”. And 12 channel Macaw image cannot be divided into 12 bands group, but only the first band can be detected. However, the EXIF tags in Tetracam Macaw-12 Channel image can be read correctly.
Could you help me in defininig the 12 bands of the images correctly.
