Import a ROI selection to Iolite (exported from the same project)

MarcoGeology2

Hi forum users,

My name is Marco. The following script is able to read a previously saved ROI containing mapping coordinates (X, Y) into Iolite v4 (Detail tab > Region of interest tab > listed here). This first version was contributed by @Joe (24 Aug, 2024).

import os
from iolite.QtGui import QFileDialog

file_searched = QFileDialog.getOpenFileName()

if not file_searched:
	raise RuntimeError('No file.')

format = ".csv"
parentDir, temp = os.path.split(file_searched)

import pandas as pd
import numpy as np

import glob

path_list = glob.glob(f"{parentDir}/*{format}", recursive = True)

for file in path_list:

	temp, filename = os.path.split(file)
	filename1 = filename.replace(format, "")

	df = pd.read_csv(file)

	imaging.spaceToChannels()
	x = data.timeSeries('SpaceX').data()
	y = data.timeSeries('SpaceY').data()

	search_dist = 10 #spot size=0.1

	mask = []

	for index, row in df.iterrows():
		d = ((x - row['x'])**2 + (y - row['y'])**2)**0.5
		mask = np.union1d(mask, np.where(d < search_dist))
	
	imaging.createROI(filename1, mask)
	print(f"Ready. {filename1}")

In the script, The ROIs need to live the in same folder and they will be serially imported to your project after the file names.

There is one issue though, I am not sure you can run (refresh) the data reduction process separately for each ROI. Also, what happens if you change your selection intervals and re-quantify? Do the ROI data (that you can re-export) updates?

I hope this is helpful.

Thanks.
Cordially,
