The loop works nicely, the output verifies that different y columns are used. BUT the parameters obtained are always identical, i.e. the fit is done only once... </div><div><br></div><div>What am I missing here?</div><div><br></div><div><br></div><div>A second problem occurs if I now mask data in col 1 ( i.e. a column not used for fitting), which generates the error msg</div><div>Python exception: There is no data to fit.<br>Traceback (most recent call last):<br> File "Test_python.func", line 10, in <module></div><div><br></div><div>Thanks in advance,</div><div>Christian</div><div><br></div><div>==> Python script</div><div><div style="margin-top: 0px;
