+## Troubleshooting: Known limitations
+
+### Failure of intermediate writing
+
+When chaining applications in-memory, there may be some problems when writing intermediate results, depending on the order
+the writings are requested. Some examples can be found below:
+
+#### Example of failures involving slicing
+
+For some applications (non-exhaustive know list: OpticalCalibration, DynamicConvert, BandMath), we can face unexpected
+failures when using channels slicing
+```python
+import pyotb
+
+inp = pyotb.DynamicConvert('raster.tif')
+one_band = inp[:, :, 1]
+
+# this works
+one_band.write('one_band.tif')
+
+# this works
+one_band.write('one_band.tif')
+inp.write('stretched.tif')
+
+# this does not work
+inp.write('stretched.tif')
+one_band.write('one_band.tif') # Failure here
+```
+
+When writing is triggered right after the application declaration, no problem occurs:
+```python
+import pyotb
+
+inp = pyotb.DynamicConvert('raster.tif')
+inp.write('stretched.tif')
+
+one_band = inp[:, :, 1]
+one_band.write('one_band.tif') # no failure
+```
+
+Also, when using only spatial slicing, no issue has been reported:
+
+```python
+import pyotb
+
+inp = pyotb.DynamicConvert('raster.tif')
+one_band = inp[:100, :100, :]
+
+# this works
+inp.write('stretched.tif')
+one_band.write('one_band.tif')
+```
+
+
+#### Example of failures involving arithmetic operation
+
+One can meet errors when using arithmetic operations at the end of a pipeline when DynamicConvert, BandMath or
+OpticalCalibration is involved:
+
+```python
+import pyotb
+
+inp = pyotb.DynamicConvert('raster.tif')
+inp_new = pyotb.ManageNoData(inp, mode='changevalue')
+absolute = abs(inp)
+
+# this does not work
+inp.write('one_band.tif')
+inp_new.write('one_band_nodata.tif') # Failure here
+absolute.write('absolute.tif') # Failure here
+```
+
+When writing only the final result, i.e. the end of the pipeline (`absolute.write('absolute.tif')`), there is no problem.
