A small bug in PolSARpro_v6.0.2_Biomass_Edition.tcl file

PolSARpro Problem Reports
#1

After I install PolSARPro 6.0 and tried to launch up sentinel 1 A/B mission, I got some error about "widget(PSPEDUC1) missing “ or alike warnings and failed start up this module.

It took me some time to figure out this is due to a misspelling in the main TCL file “PolSARpro_v6.0.2_Biomass_Edition.tcl” .

at line 48859, "$widget(PSPEDUC1) configure -state disable "
and line 48931 "$widget(PSPEDUC1) configure -state normal ",
“PSPEDUC1” in the brackets has to be changed to “PSPEDUC”, then it will work.

this message is for those who may encounter the same problem.

thank you for sharing. So you mean that the 1 has to be removed from these lines of code?

#3

I am not really sure if it should be removed or not(I do not know Tcl/Tk), but the sentinel 1 part won’t work and raise error messages with this 1.

@szw it worked for me I can say thank you so much

Hi,

I hope my error is related to here.
I installed PolSARPro biomass edition with all the required softwares. But it is showing “can’t find package BWidget” error while entering.
I downloaded the latest version of BWidgets package and unzipped in TCL lib directory. As mentioned in widgets folder, thought of appending auto path variable and adding " package require BWidgets" line will solve the error. But I don’t know how and where to add that and ended up here. @szw Can you help me in which file to change that line??
Any help in solving this error is appreciated. I here attached the screenshots of error messages too.

Hello,

I encountered the same issue when trying to lunch Sentinel-1 A/B mission.

I did try to edit the TCL file “PolSARpro_v6.0.2_Biomass_Edition.tcl”, but apparently we cannot (and shouldn’t?) edit any TCL files.

Following is my error message:

can’t read “widget(PSPEDUC1)”: no such element in array
can’t read “widget(PSPEDUC1)”: no such element in array
while executing
“$widget(PSPEDUC1) configure -state disable”
invoked from within
“.top3.fra66.cpd69.but93 invoke”
(“uplevel” body line 1)
invoked from within
“uplevel #0 [list $w invoke]”
(procedure “tk::ButtonUp” line 24)
invoked from within
“tk::ButtonUp .top3.fra66.cpd69.but93”
(command bound to event)

Any ideas?

Hi samlee, I have encountered a similar bwidget package problem. I was wondering how you actually fixed the issue. I am not sure where I am supposed to put the BWidget folder downloaded from online.

I hope you can help.

seems like a file permission issue, check if your tcl file is read only or belongs to a user group you do not have write permission.
