  • Fixed an indexing bug in aedes_readfid when reading multireceiver

EPI data

  • Added EPIPhasedArrayData -property to aedes_readfid for manually

getting the data from individual coils from multireceiver EPI data

  • Fixed aedes_rot3d to work with n-D arrays
  • Added 18 new ROI colors and removed the ROI number limitation
