Hi. I am running PyCharm and I have an issue which I don't understand.
thanks,
M
import numpy as np
import matplotlib.pyplot as plt
def ROIselection(mat):
plt.imshow(mat,cmap='gray')
plt.title("Click 4 times, vertices of a rectangle")
plt.show()
pts = plt.ginput(4)
pts=np.array(pts)
mask=np.zeros(mat.shape)
xvals=pts[:,0]
yvals=pts[:,1]
mask[int(np.min(yvals)):int(np.max(yvals)),int(np.min(xvals)):int(np.max(xvals))]=1
return mask
mat=np.random.rand(10,10)
ROIselection(mat)If I copy and run this in an ipython terminal, there are no issues, works a charm. If I run this as a script in pycharm, the markers do not appear in the figure, and nothing gets saved. This is probably something silly, but I don't get it so would appreciate the helpthanks,
M
