I am running Analysis 1.0 release 6 under linux. Most functions seem to work well including pick peak (with left + control), but pick peaks in region (with left + control + shift) and depending on the order i press the buttons either i draw a box and nothing happens, or i draw a box which doesnt go away until i click the mouse somewhere else and i get the following message. Exception in Tkinter callback Traceback (most recent call last): File "/usr/potato/bmbsjp/bin/ccpnmr/python2.4/lib/python2.4/lib-tk/Tkinter.py", line 1345, in __call__ return self.func(*args) File "/home/bmbsjp/bin/ccpnmr/ccpnmr1.0/python/memops/gui/ScrolledWindow.py", line 982, in <lambda> cmd = lambda event, button=button, state=state: self.releaseFunc(event, button, state) File "/home/bmbsjp/bin/ccpnmr/ccpnmr1.0/python/memops/gui/ScrolledWindow.py", line 955, in releaseFunc func(event) File "/home/bmbsjp/bin/ccpnmr/ccpnmr1.0/python/memops/gui/ScrolledWindow.py", line 1461, in selectRegion self.select_multi_func(event.widget, a0, b0, a1, b1, x0, y0, x1, y1, button, state) File "/home/bmbsjp/bin/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/WindowPopup.py", line 1837, in selectMulti self.examineRegion(canvas, a0, b0, a1, b1, x0, y0, x1, y1, state=state) File "/home/bmbsjp/bin/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/WindowPopup.py", line 1811, in examineRegion thickness=spectrum_thickness) File "/home/bmbsjp/bin/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/PeakBasic.py", line 1422, in findPeaks diagonal_exclusions=diagonalExclusions, excluded_regions=excludedRegions) PeakList.error: need arguments: first, last, block_file, [ have_low, have_high, low, high, buffer, nonadjacent, drop_factor, min_linewidth, diagonal_exclusions, excluded_regions ] Has anyone got any suggestions Cheers Stephen
