我想在Python中使用bioformats讀取顯微鏡圖像(.lsm,.czi,.lif ,你將其命名),打印出元數據並顯示圖像。 ome = bf.OMEXML(md)
給我一個錯誤(下面)。我想這是關於存儲在md
內的信息。它不喜歡md
中的信息不全是ASCII。但是,我如何克服這個問題呢? 這是我寫的:Bioformats-Python錯誤:'ascii'編解碼器無法編碼字符u' xb5'當使用OMEXML()
import Tkinter as Tk, tkFileDialog
import os
import javabridge as jv
import bioformats as bf
import matplotlib.pyplot as plt
import numpy as np
jv.start_vm(class_path=bf.JARS, max_heap_size='12G')
用戶選擇文件中numpy的陣列
raw_data = []
for z in range(iome.Pixels.get_SizeZ()):
raw_image = reader.read(z=z, series=0, rescale=False)
raw_data.append(raw_image)
raw_data = np.array(raw_data)
展上展出了元數據與
#hiding root alllows file diaglog GUI to be shown without any other GUI elements
root = Tk.Tk()
root.withdraw()
file_full_path = tkFileDialog.askopenfilename()
filepath, filename = os.path.split(file_full_path)
os.chdir(os.path.dirname(file_full_path))
print('opening: %s' %filename)
reader = bf.ImageReader(file_full_path)
md = bf.get_omexml_metadata(file_full_path)
ome = bf.OMEXML(md)
認沽圖像工作
iome = ome.image(0) # e.g. first image
print(iome.get_Name())
print(iome.Pixels.get_SizeX())
print(iome.Pixels.get_SizeY())
這裏的e RROR我得到:
---------------------------------------------------------------------------
UnicodeEncodeError Traceback (most recent call last)

這裏有一個代表test image專有顯微鏡格式
你可以添加上傳一個示例圖像嗎? –
@MaximilianPeters,我剛剛添加了一個.lsm文件進行測試。任何建議,將不勝感激。謝謝! – puifais
