I understand you want to create a function in MATLAB to find the peak coordinates in a zmap within a region and use it as a seed region.
You can create a MATLAB function to find peak coordinates within a specific region in a zmap and use them as seed coordinates for further analysis. Here's how you can approach this task:
- Load the Z-Map Data: Begin by loading your Z-Map data into MATLAB. You can use functions like load or appropriate data import functions based on your data format.
- Define the Region of Interest (ROI): Define the region you're interested in, in this case, the Posterior Cingulate Cortex (PCC). You'll need to have a mask or coordinates that represent this region.
- Extract Z-Scores in the ROI: Use the ROI information to extract Z-scores or relevant data points from the Z-Map within the defined region. This will give you a subset of data that corresponds to the PCC.
- Find Peak Coordinates: Apply a peak detection algorithm to find peak coordinates within the extracted data subset. MATLAB offers functions like findpeaks for this purpose.
- Get Seed Coordinates: Once you've found the peak coordinates, you can use the find function to obtain the indices of these peaks.
- Further Analysis: You can then use these peak coordinates as seed points for further analysis or connectivity studies.
